square wave tig

[mattc]

has anyone worked with the Lincoln square wave tig, I have a friend that is selling one and want to know other peoples openion, is this a good beginners machine for alum and steel

What size?
I've got a sw 175 that i got cheap. i wouldn't buy one again, Kinda small for me.
Works good on thinner steel & stainless. Stick welds good.
Not happy with the tig performance on alum. not good for much over 3/16 alum.
When i buy another tig, It's gonna be a 300+amp inverter machine. But its a decent starter machine, in my opinion.

My SquareWave Tig 275 has been a great machine....

personally agree with BB you will wantnothig less thann 250 and a 300 is better. Going to helium helps a lot, but its more expensive too. Depends on how much you plan on doing you could easily pay the differnce of the welder in the cost of helium.

I have a square Wave Tig 355. Truly awsome. 2-420 amps. Comes standard with pulse, balance control, up slope, down slope, spot, start control. etc.
