This is my first post and I am sorry it's a negative one, but I am at my wits end.
I just bought a 256. Friday I did some test ac welding, about 15 minn. of use. Worked great. When I came out sat. to start a project and as soon as I hit the peddle to start the pre flow, the over current light comes on and it doesn't put out a full arc.
I called Saturday late morning and never got my call returned. So I called again Monday early afternoon and still no call back!! What do I have to do to get my called returned?

I am very frustrated and loosing confidence in this product.
