a couple starion 2.6 owners diy MIG weld modified their imported fwd Mitsu magna
Somebody brought a friend an Eastwood MIG to weld on a cut-off bellhousing ring to agapt another gearbox
After using the MIG, he purchased one to do 90% of his aluminum welding
He says its wayyyyyy faster, less fussy, cheaper and easier than the TIG
So his big old Miller TIG collecting dust in his workshop (PC board failed twice, no interest in fixing it again)


Another buddy is a rotary enging guru, who Stick welded(big ol Lincoln DC) all his aluminium way back in the day
I'm no pro, but the welds look good to me, and most importantly.. zero failures. His street car scared the crap outta me
