This industrial power tool was a disappointment. Thanks to my knowledge gained in practice, I found that the quality of the welding was subpar. Even though it is marketed for welding stainless steel, it did not produce a clean and polished finish. The handle of the tool was also uncomfortable to hold for extended periods of time. This product did not meet my expectations, and I would not recommend it for use in the industrial and scientific sectors.
Don't let this ad fool you like it fooled me! This wire is about the size of a spool but it shows a full size spool like so many other sellers I've seen after buying it!
I got this from fitting a stainless exhaust to my C10. You can use ordinary carbon wire, but stainless steel is better. No complaints. I used my regular Ar/CO2 gas and it works great too. Maybe more spatter and a darker weld, but that's not an issue if you're sanding or painting it.
