FYI"
If you're building a mild steel chassis for certification it must be either mig or tig welded only. ( chromoly Tig only). Not saying you are so it may not apply. Just that if that's what they (SFI & NHRA) consider safe............. well it's worth considering a mig welder. They are relatively inexpensive and make a nice weld. Not saying you can't use a stick welder, just offering an alternative.
