I can't imagine the average guy not being able to get by with .045 wire for general fab work. That machine should just scream with .045! And if you wanted just a little more pop, you could go with 100% CO2, instead of 75% argon & 25% CO2.
Then there is a whole other world of dual shield wires also.
I've had very good luck with Lincoln's L-56 wire. http://www.lincolnelectric.com/en-us/Consumables/Pages/product.aspx?product=Products_Consumable_MIGGMAWWires-SuperArc-SuperArcL-56%28LincolnElectric%29 This post was edited by Puddles at 01:47:16 11/11/12.
