Could you guys point me in the right direction with the basic setup for my tig?I want to practise welding aluminium (looking for a night class at the moment) with my machine, alloy is .080 thick and machine is ac/dc inverter type tig, I'm thinking 80 amps? but what about the AC frequency and AC balance? and what effect do they have on the actual weld? (I won't mention pulse mode, that's got me real confused!). I've got white tip (zirconiated) tungstens, do I grind a small point on these or just leave them? Any help would be great. Thanks.

Reply:Basic setup would be about 80 amps AC, HF start turned on, 60Hz, 30% cleaning, 3/32" red, gold or white tungsten, sharpened to a point, argon about 15 cfh, 1/16" or 3/32" 4043 filler rod. That should get you in the ball park and able to weld something. If your machine has an owner's manual, it may have better parameters listed specific to that machine.MM350P/Python/Q300MM175/Q300DialarcHFHTP MIG200PowCon300SMHypertherm380ThermalArc185Purox oaF350CrewCab4x4LoadNGo utilitybedBobcat250XMT304/Optima/SpoolmaticSuitcase12RC/Q300Suitcase8RC/Q400Passport/Q300Smith op
Reply:I agree with everything DR said except the 1/16" filler. I've been hobby TIG welding for awhile and I've been in TIG class since August. Self taught before classes, 1/16" filler was the biggest obstacle in my learning and still gives me a headache.If you decide to use 1/16", keep your torch as close to 90* as possible or the filler will melt well before it gets to the puddle.9-11-2001......We Will Never ForgetRetired desk jockey.
