I have had a Trailerblazer 280NT and used it with a spoolmatic for years, but after buying a Super SP32 which was more "portable" to other welders and allowed the large spools I sold the spoolmatic. The other day I tried to hook up and weld with the Super sp32. I had terrible luck getting it to work. The arc keeps jumping up the wire and blowing it out.
I have tried both CV and CC modes as settable in unit. Also tried electrode both negative and positive.

I must be setting something wrong. But no matter what I tried it still flames out.

Any ideas on what is set wrong.
