Just received my new PA140ST. Hooked it up and welded some 3/32/6011. It was a supprise when the rod burned though 1/4 plate at 95 amps! It is amaizing that something the size of my grandson's lunch box has that kind of power. I noticed that the 5 foot leads are a concern on line. My unit came with 10 foot plus all copper leads. I have to go to Paxair tomorrow for an argon tank. Have argon/co2 for my wire welder but they say not to use it with tig.
