Your 141 is rated to 3/16" - so frame mods are about at it's max - but certainly doable. What people don't factor in when buying welders etc is the DUTY CYCLE.... yours is rated 90 Amps @ 20% Duty Cycle. There's where the price of the machine etc make it a "home owner" or light duty machine. My 211 has a 160 amp @ 60% duty cycle rating.
Given that most of our welding for hot rod projects are for short bursts... some of this is perfectly adequate. It wouldn't be if we were in a job shop trying to crank out parts all day.
