  • Well the saga continues….. Since the last laser post, the Customs and Border Patrol (CBP) and the Food and Drug Administration (FDA) have been playing catch 22 with me. Neither has ever destroyed a laser device before, and can’t decide how. To make things worse I am stuck in the middle. CBP needs a form, FDA does not know who fills it out. Then Good old Washington State EPA requires a license for the recycler. No one knows what is going on. The welder has a water cooler, and a refrigeration system. When I told the FDA the unit contained dihydrogenmonxide DHMO (water H2O) and a HFC 409 and their head exploded. The EPA and FDA spun up and can not decide what to do. CBP treats it like a bad batch of apples but won’t issue some release form to FDA with out a HAZMAT determination. Today I am still waiting for CBP form 4647..

    Can this get worse??? Why sure

    The manufacturer says they will replace the unit under warranty and has shipped the new one door to odor from the factory. (They exported it before it was approved for entry into the USA). That is good if they really did. I finally convinced the vendor, the customs detention and failed inspection was on just my machine only, not all of them. They played stupid until the last minute until I sent a threat to have them banned in the USA for non compliance to the CFR, and be put on the no entry list. Nice to be retired navy, and have an Admiral in charge of Radiation health (CDRH). So maybe new machine, dingers crossed
    Then I sent the customs forms to AMREX, asking for an insurance refund on the purchase. They went to eBay with a dispute, eBay then held the amount from the vendor. Then eBay rejected the dispute and still have not released the funds. So the Manufacturer will not release the warranty replacement from bond until it clears. 10 calls and emails to AMERX and eBay can not seem to clear the dispute. My account shows no disputes, vendors says still pending.. So I broke the welding unit down into several piles of parts. Laser stuff, power stuff, cooler stuff, computer stuff, preparing for disposal. Several piles all covered by different state recycling laws.

    On a more positive note, this machine is amazing, the welds, cleaning, cutting etc are like the videos. It take a couple hours to to figure it out. The chinglish manuals are not easy, but after you have gone over them 4-5 it starts to make sense. It’s just like MiG, except the wire feeder pushes the gun, and the nozzle needs to rough the material being welded, not as a ground but to keep the beam at the weld and not the shop. We only got a few hours on it before I had to brake it down. Welds 0.5mm wide in 18 ga steel, spot welds like a pro, cuts up to 10mm thick, cleans paint, dirt and corrosion with ease. Does heat the metal up some, but no more that a car in the sun in the summer. the YouTube videos ate real, takes some practice but works. Uses Nitrogen to blow on the lenses to keep them clean when cutting . I will try clean dry air when the next one arrives.

    enough for now, cross your fingers, I may get through this yet.

      Wishing you a positive out come on this in the new year John. This is a tough one to swallow for sure. On an another note can you post a detailed photo of the spot welds you are able to produce?

  • Welder saga continues. Good news, the E-mail this morning says the warranty replacement welder is ready to release and delivery. 90% confident its here, until I lay my hands on it I will remain skeptical. Seaman Laser LLC in China says it here in the bond warehouse, a will be delivered shortly. Then I get to start all over again, but with no FDA an its through customs. With 150 emails back an forth with the manufacture over the summer I must say they are very good, but the language barrier was difficult. Once I got the factory to understand that only MY UNIT failed the customs inspection not all of them the fog lifted. Also the customs entry form they sent, to clear US customs entry was not filled out correctly and did not list the required model an part number, ( it just said "LASER WELDER") . That paperwork error was what triggered the incoming entry FDA inspection, that cascaded into a bunch of other regulations and more misery. It was their fault in the beginning. It was advertised with a 5 year warranty, and they say they are making good on it. I remain skeptical.

    The FDA and US customs are in a catch 22 on the forms and procedures. Seems they have conflicting requirements. Neither has destroyed one before and can not seem to get all the paperwork together. I did my part, on time, but finding a Washington state license recycle facility that can take refrigerants, electronics, and dihydrogenmonxide (H2O) in the same unit does not exist, and no one wants customs and border protection (CBP) on their property for some reason. Anyway they say next week they will have a plan. FDA and CBP have decided to destroy it here on sight, to avoid the state ecology regulations. That is a good thing,

    Anyway I removed the RACUS fiber laser source, from the rest of the welder (photo below). That separated the FDA regulate component from the rest of the State EPA regulated components. That allows the FDA to inspect it, complete a form for customs and certify it destroyed. Now I was very careful while destroying this machine. If they don't take any parts away with them, Justin may have a pending deal in the works. In spite of all the BS an worry it has cause, this is a great welder and it does all the stuff in the YouTube videos just like they show. I was a little skeptical in the beginning but this thing is really cool.


    justin…. Your spot weld photos, these were the first few I tried, various power and sweep rate and time settings .left side is top side, right is the bottom. Most are .035 ~ .075 seconds of time longest was 1 second. Power between 20-35 watts. about 4-5” off the metal, point and shoot. Pretty easy.

    • Been a couple months since I up dated the laser saga. CDRH / FDA field inspector came out last month and determined the machine was destroyed. Field inspectors submitted the report stating such, Finally. The Seaman CNC ( eBay goldcnc) claims to have shipped a warranty replacement, “ door to door “ back in December. They say it arrived in Feb. All last month it was being trucked to me. Now they have received a “customs invoice” Delayed delivery. one delay after another, I might be being played. But the eBay price has dropped to 1/3 of original price. I have another 356 guy that bought one from them, it arrived a few weeks ago.

      but I do have finally good news on the laser. The FDA and CBP customs entry headaches are over. It’s out of customs detention, officially destroyed, serial number tag removed! This week I spent a couple days repairing cut wires, reinstalling the computers and laser source and yesterday afternoon we plugged it in and filled the cooler with water. After 4 months I might be back in business. Thank god for google translate, we do not have a wiring diagram, only a chinglish manual.

      I also stumbled across a local fabricator a couple miles away. Another friend ask me to go over and look at his laser cleaner. He could be my clone. Just like me, but 30 years younger, but retired navy officer, same career path, same specialty designator, even a couple of the same jobs. Jess Halfacre at Halfacre Fabrications has a YouTube channel and is building a 57 Chevy from scratch. Very well tooled, not afraid to try or buy something and self taught . Has Lathe, Bridgeport, welders, fab table, bead rollers, he has everything. He a 72” 20 ton press brake, with a digital readout and a laser guide and its numerical Controled. I did not even know they made those. Excellent panel beater fantastic welder, We will use the my laser on the 57 and adapt the cutting head to his plasma table. Take a look at he YouTube channel watch and like his videos.



      thanks for looking

      • Still no updated status on the warranty replacement, beginning to think I have been scammed, but I still can get eBay back involved. The old unit is back together, seems to work, got 20 minutes out of it cleaning, befor get a contaminated lens from the smoke blowback and exploded a protective lens. Had a Loud pop and we’re done. Have not got too deep into it yet, but it welded and cleaned fine….

        Did a wheel cleaning for the 56 coupe. Another thing misplaced by the previous IDIOT. Took about 10 minutes to bare metal. The black looking carbon coated area is where I have burned off the original paint. Wipes off with a soft brush. Celeste bought a used wheel from eBay, typical not even cleaned before shipping, the inside was coated with dry grease and dirt. The laser made quick work of the mess.

        • Wheel and carb day. Got the spare wheel primed and painted. A couple hours in the oven between coats worked fine. Laser got the inside so clean, just a wipe with scotch bright brite and shoot. Couple hours at 150 between coats, works well.

          Nothing special, but did run into an interesting Zenith float valve. The new kit has an 18mm long vice a 15mm stock. Actually a good thing I did not have to add the usual 0.1, 0.2, 0.3 extra shim stack under the 1.5mm seal washer to get the float set. I put the carb on the bench a the original valve was about 3mm high using the P-Tool. New one fell right on the mark. Drained the bowel exactly 50ml. Also these carbs are very old, grey/silver floats, still had the rivets in the top gasket.

          • The below should have been posted to the 56 coupe.

            But here is a link to the laser cleaning a set of tin on YouTube. The flame is old dried oil and grease. The paint just turn into smoke. Rust just disappears and the metal is clean. Some carbon dust but amazing. This worked super, a light scrub with grey scotch bright pad and into the power coat oven.

            • Getting bored here!

              A NEW toy build. I came across a DYI Plasma table. Cheap to build (I think) its small ~30" x 30" pretty light and held in place by electromagnets, So for some small parts and quick fabrications, I can just stick it on a sheet an cut it. I plan to build it so I can use the laser cutter as well as a plasma cutter. It was design by JD's garage on YouTube. Plans were 35 bucks, 3D printed parts AND a few stepper motors. Should work well with the laser since there is no EMI or interference from an electrical arc. Of course I will still build it for Plasma arc and a high speed spindle also.

              The entire unit is 14 pounds, it can hang on the wall so it wont take up much space with not in use. Each foot is a 70 pound pull so it should be stable even up side down. I will do some modifications to this original design with a torch height sensor that will let me control the cutter to material distance and eventually a 4th axis driver to notch tube an pipe . I will also add some E-stop an limit switches to the design, but another challenge will be re learning the programming and control software, but what the heck,

              link to a video of the unit, looks like a door shin remover

              • Parts coming in this week, the build begins.
                A friend did the 3D printing for me, I bought a spool of filament and gave him the files. My first real exposure to a printed plastic part. Very impressed with these. I started to assemble the frame today, awaiting parts on the M5x12 screws, tried x14’s but too long. I did use them as placeholders. So far it looks adequate for my needs right now.

                The entire unit is a little over 2x2 foot, square, hangs on the wall so no lost floor space. It has electromagnets for feet on the corners. So it can work a metal sheet that's been leaned up against something. I figure most brackets and parts we make are small so this should he better then the saws and files we use now. We have the laser and three plasma cutters so it will get used. i will need to modify it for the laser cutting, but it’s been done before so it’s design and print an adapter for the gun. I also plan to make the Z axis movable with a torch height controller. We are also looking at a Tube / Pipe cutting accessory for roll bars and kangaroo catchers. The GRBL control board is reasonable and has Wi-Fi and Bluetooth radios built in, a small color touch screen. It all runs on 12v 600w.

                Software and computer CAD/CAM drawing I’d fun to learn. I did auto cad years ago (right after the Chinese invented arithmetic) and way before the mouse, so it the basically the same I just can’t “put line” anymore. Icons and pull down windows galore, but what ever is free either Sketchup or Fusion 360. Seems straight forward, Do the design in CAD the save as a CAM then Wi-Fi to the table as a GRBL as a cut path.

                • We progress. got the gantry installed. these parts are very tight, I am really impressed with the printed parts. He printed the parts with 0.0005 tolerance which is good, but all the parts are tight. To assemble the axles into the gantry, they had to slide straight on parallel to the other half, no wiggle room which is good. but there are allot of parts to keep straight, The step by step directions are very good, an you need to follow the assembly sequence, or end up redoing some steps. I plan to add a Z axis to it later with a torch high controller (THC), and eventually add a 24V high speed Spindle for carving or engraving. So far it’s coming in at budget even with a couple upgrades. Building on a table saw for size reference.

                  Software is going to be the hard part if your old. It’s coming back slowly, lots of new features in 30 years. I start with "Autodesk Fusion" to do the 2D drawing ( because it free ) then produce the tool path. Fusion is very powerful it does 3D, 2D, sheet metal, electronics, house wiring, anything you can draw on paper, but with way more pop up windows than I can keep track of. Once the drawing is done and the cutting path is verified by the CAD automation, the file exported to "OpenBuilds Control", that writes the GRBL code to run the machine. This is pretty good a capable software, It allows you to run the machine, test the tool path, edit the code if required and flash the DLC32 board if required. The interface to the machine can be WiFi, USB or Micro-SD card. The Board also has a 3X4" touch screen right on the machine for additional control. You can do a drawing at the home office here and send it to the machine via the internet 30 miles away. pretty slick i think.

                    • Get out the squares..

                      Did the alignment and final axis adjustments. Went fairly easy but did require a complete disassembly and reassembly. Put it together installed the drive belts and got it ready to run. The squares and vice grips hold the extrusions square while you tighten the screws. I must admit it’s came out perfect, Could not get a 0.0005 feeler gauge between the rail and square. ITs has gone together pretty easy so far, vert tight fits and seems stronger than I expected. Also the metal to cut can be bought by the sheet or I like 6" flat bar which is pretty easy to find and store for brackets.

                      The software Autoesk Fusion and Opensource is well supported and has pretty good user groups. There are also several other free programs like Sheetcam etc. The process is not too complicated. You draw the part, then process it into a cut path. then export it to the OpenSource to operate the machine code (GRBL) I will admit its complicated setting up cutting speeds lift heights initial machine parameters, but once that's done you finished. you save that in Fusion as a tool. now the cut paths will repeat each time. You can have several versions of each machine in tools for different materials, thickness etc. The user groups have tons of cut ready DXF or other format drawings for free or for sale. d

                      the FireBall tools squares are amazing. As you can see they are wide and unusually shaped, but we progress, Fireball makes fabrication tools for welding, the best you can find.

                      JD's Garage just dropped a metal version if you don't have a 3D printer. its basically the same design except you can print full size drawings and glue them to the metal, cut out the parts with a band saw. It also have STL files so you could have them cut by a plasma. or they sell the parts pre-cut. parts list in complete and available;e from amazon or aliexpress . lead time from china is about 10 days. and as a side note When you order the DLC32 BOARD, get the TS32 LCD larger screen not the TS24. Also I ordered extra belts and screws now for future spares.

                      More details here.
