clark welders

I have the little Craftsman 85 amp mig. It's made by Clark. Best welder I have ever owned and I had a huge Millermatic that crapped out before I got this one for father's day. The Miller could certainly handle heavier stuff, but the Craftsman is much more precise. The only one time I ever had a problem.....and it was VERY similar to what you describe was when I used an under rated extension cord.
