Father-Son 1974 Duster Project

I'm using the $100 blue fluxcore HF welder
I got mine used from a Dude on Craigslist for fifty bucks!
It works great for what it is. The flux makes a residue but it cleans up well with laquer thinner

How thick of metal will it do before it runs out of steam?
I keep having people telling me to "not waste my money on HF crap and buy a GOOD welder"....but honestly, I just need something to do small work such as what you are doing. Dropping $1500.00 on a Hobart that will spend most of it's time sitting in corner just isn't part of the plan. Do you think it would have enough mojo to weld on the subframe connectors I wanna buy? They are bolt-on/weld-on and I'm planning on installing them as bolt-on's but would like to final-weld them before I drive the car.
Sorry if I'm hijacking your thread...
