Reply:What exactly are you stuck on? Thats a great little machine and does a real nice job if you get it set right.Id set it at200A on the dial70% balance120HzHave we all gone mad?
Reply:Thanks it seems to be running smoother but I'm still having trouble holding the puddle together. Any good ways to better control the heat affected zone?
Reply:Keep your tungsten close, within 1/8" of your puddle.And watch your torch angle."SOUTHPAW" A wise person learns from another persons mistakes;A smart person learns from their own mistakes;But, a stupid person.............never learns. |
