Is it possible to use these for 1/4 or 3/8 steel in multiple passes? The one I am looking at says up to 1/8"  and uses 1/16 rods.  I just need this for very casual use.Thanks
Reply:Not really. If you want to just stick metal together for say an art project, then yes, but the welds really won't have any strength. The weld won't fuse well to the base metal with that small a machine. To weld 1/4" or 3/8" well, you really need to get a 230v machine or spend big bucks on a top of the line inverter like the Miller Maxstar or Dynasty if you must use 110v power..No government ever voluntarily reduces itself in size. Government programs, once launched, never disappear. Actually, a government bureau is the nearest thing to eternal life we'll ever see on this earth! Ronald Reagan
Reply:I will tell you straight out.All my welding is done at 100 to 150 amps.Baby welders cant do much welding.1/8  rods on 70 amps is a lie...
Reply:I tried that, don't bother.  The welder will get hot and shut down, then you wait 30+ minutes for it to cool and "attempt" another pass.  Had a Clark 110 AC unit when to 90 amps I believe and didn't come close to doing what your wanting to do.
Reply:Depends on the welder. My Miller Maxstar 150 STH will burn 3/32" 7018 all day long on a standard 20 amp 120v breaker (probably even a 15amp breaker) . The thickness is really only limited by how many passes you want to make.Shipwreck tools special? don't count on it lol.Welding/Fab Pics: www.UtahWeld.com
