I had a hard time getting the filler to melt. The filler rod would stick and it would burn a whole in the metal before melting the filler rod. My electrode was 1/8" and so was the filler. I assume that is the problem.  I was welding 1/16" sheet metal. I also tried welding two box knife blades and blew right through it at 10 amps. Is the large electrode to blame?
Reply:no, your amps are too high and you're not using a pedal for metal that thin.Go get a 3/32 tungsten and try running carbon wire on a carbon plate.
Reply:What do you mean by "I'm not using a pedal"? Should I use the pedal for thin metal.  Because I tried the pedal but I just didn't feel like I had good coordination so I switched over to the button. I tried all different amp settings is 10amps to high?
Reply:On thin metals you generally use high frequency welding because you can control the heat output. the 1/8 wire (not rod) was waaaaaay too thick for such thin metal. I'd suggest look up a tutorial on "Micro Welding"
Reply:Ok will do. thanks for the tip.
Reply:For 1/16" steel try 1/16" filler wire or smaller. A 1/16" or 3/32" electrode is what I would use, ground to a sharp point.Airco Ac/Dc 300 HeliwelderMillerMatic 200 (stolen)Miller Maxstar 150STLMiller AEAD200LE (welding and generating power) Hobart MIG
Reply:Get 1/8" steel for practice.Use 1/16" filler, 3/32" tungsten sharpenedUse your pedalRun some beads and post the pics.Include all information on machine setting, gas flow, tungsten type/size, cup size, etc.Dave J.Beware of false knowledge; it is more dangerous than ignorance. ~George Bernard Shaw~ Syncro 350Invertec v250-sThermal Arc 161 and 300MM210DialarcTried being normal once, didn't take....I think it was a Tuesday.
