TIG or MIG welder

[magicniner]

MIG ......... It's ideal for mild steel down to 2mm - 3mm thick. Anything less than 2mm thick will be best welded with TIG.

That's innacurate information and as a former Vauxhall Dealership Panel Beater and Jig Operator I can inform you that body steel down to 0.8mm is easily welded with MIG and CO2, ESAB set bodyshop proceedures for this using 0.8mm wire, thinner material than this is better welded with 0.6mm wire, some good MIG sets designed for lighter work will have an intermittent setting to help welders who are unable to deal manually with thin material,
Regards,
Nick

I didn't say it CAN'T be done. For "on the bench" type work, TIG does a nicer job of sheet metals and gives better pool control, particularly for none-expert welders. I also said that thinner materials could be welded but you generally have to "spot" weld to avoid burning through if you're not an expert. I've welded cars with an arc welder in the past but I wouldn't recommend it.
