Re: [CAD_CAM_EDM_DRO] Digest Number 1046

Well not knowing any better, I rewired my house and used #2 wire and a 100
AMP breaker with a 200 AMP main... I figured overkill would not hurt... I
have used my at full duty at my shop though with much thinner wire and
only a 50 AMP breaker. I have a ProCut 25 that I use with 230v and I
really wish I had the ProCut 55.

When you weld on thick Aluminum you really challenge a small TIG welder
like this because Aluminum sucks up the heat so well. I love the
Squarewave 175 I have... totally simple to use and makes a nice weld...
even an amatuer like myself looks good using it.

Hell even though TIG is more "expensive" than stick or flux core welding,
I use it for everything since it never makes a mess.
