Its certainly do able, but I can't believe they are doing it by welding a couple inches, and walking away for several minutes to allow it to cool before coming back and welding the next couple inches. Nor are the welds pretty enough to indicate they were robot welded. Even on 0.100 I can't run continuous beads very far. If everything is just perfect you can get maybe 6-8 inches before its to overheats and drops out. I am looking for something better.
I was told that a pulse MIG was the way to do this, but it sounds like from the way this conversation has been diverted that an Everlast pulse MIG can't do it.
(Actually to be fair Tracker is probably robot welding on their newest boats. They have gotten so big compare to other aluminum boat manufactures that it makes sense for them.)
Robot or manual makes very little difference. If your parts are not pre-heated to soak temp, you will need a spoolgun with remote control, or a machine with a programmed mode. Once you build some heat, you can back off the current(wire speed) and rock on. True, standard or pulse on pulse would help, but it is by no means required. At the moment Everlast has several standard pulse models, but no pulse on pulse models, that I am aware of. You might call to check the industrial line as I have heard there are other machines there, that are not listed on the website.
