I got an inverter MIG off e-bay and its been a revalation now I've learned to trust it and let it do the ajustments not keep fiddling with it. Planned to do gas but got a reel of gasless as my first job was repairing a mower. Gasless came out better than gas with my old MIG so I'm staying with gasless for the Sankey floor as I have to work outside and the breeze blows the gas away unless I have it turned up a lot. Get a top notch auto helmet, worth the extra, i had a cheap auto, not the same.
