Maybe a dumb question but we have this machine at work and im not a pro welder but dont suck at it either lol question is, is this machine a traditional square wave style or is it an inverter square wave style. Reason I am asking is because i am gonna fab up some aluminum brackets and the material is .065 wall thickness and the tungsten that is available at work is 3/32" with 1/8'' filler rod but according to the Miller Weld Calculator it suggests 1/16" tungsten and filler rod. And then specs either green banded tungsten for traditional square wave vs. gray banded tungsten for inverter style square wave. Just need to know what i am gonna need before i start. thanks in advance
