A tip; don't buy Super Six gasless wire. If you find a stockist of Lincoln wire, get it. I was going bananas trying to get a decent gasless weld with Super Six until I found a local stockist of decent wire, namely Air Liquide Weld Team wire and not much more costly than Super Six anyway, only a quid more per small reel where I am.
I can see how many people think gasless is crap, and truth be told, in a lot of instances it isnt as good as proper argon-shielded MIGging, but it does a job and with the right tools, materials and techniques it can do it well. Gasless welding gets a bad name because of crap wire like SSix (and possibly some users who simply can't learn it anyway).
Typical. Just got two roles of super six!!
They might still be an improvement on the wire that came with it!
