I bought a stick welding system 80/160 amps from Harbor Freight some time ago, just because I got a good deal and figured I'll surly use it some day. I had already bought a mig from them which I have used very much and really never needed the other welder. Now I need to weld stainless steel so I figured it's time I set up this welder. I'd welded with I assumed every welder there was in 22 years before I retired but I have never come across a welder with no settings control. Also it came with no manual or model number, all I have is a item # 02665. I hope I can get some help, instructions, or manual.
