Hey guys. Looking to get a spot welder to do my sheetmetal work on my charger.

Looking at a miller lmsw 220v with 6" and 18" tongs or a Lenco 4000 mark ii. Has anyone used either of these? They both seem to have their advantages and disadvantages but I can't swing both of them.

Going to be doing the trunk floor, extensions, quarters, tail panel, balance ect....

Thanks!
