Reply:The size and type of tungsten depends on the amperage range and materials (and even torch) you plan on using. Need more info.Welding/Fab Pics: www.UtahWeld.com
Reply:i prefer red or gold band tungsten though. For scratch start, just make sure you have that SHARP, you want it needle sharp it will make starting the arc so much easier on you. If you keep it sharp and clean you should barely have to touch the tungsten to the work to get the arc going.ESAB MigMaster 275Miller Econotwin HFMiller Syncrowave 250
Reply:the torch is rated to 150 amps that about the max i would do. i would be using this for thin stuff also like maybe 1/8 inch if i could2-Lincoln idealarc 250/250, lincoln 225 ac/dc welder, lincweld ac 180c, hobart handler 210, hobart stickmate lx 235/160, Hypertherm Powermax30local 26 I.B.E.W Electrician
