Anybody own one of these

The reviews recommended using Lincoln .30 wire instead of the wire that came with the welder.[/QUOTE]
It depends what you're welding. If your'e welding up a trailer hitch then .030 wire is good. It takes more current and heat to melt it and the base metal. If you're tacking a patch panel on your 1/4 use .023 wire on a low setting so that you don't build up too much heat and warp the metal.
