I will probably end up walking bowlegged fir this but.....
If you aren't going to be doing production work, or building a balls out race car/truck/buggy, then I'd look at the Harbor Freight welders. I bought one for my father years ago as a Christmas present and I have run a spool and a half, maybe 2 through it since then. It's the dual Flux/mig unit and has served me well through the years using flux wire. I have been too cheap and lazy to buy a tank and gauges. I welded a door hinge back onto a Dakota door, and made a front hitch that has held up to pulling trees with full throttle assaults. I have welded exhausts, both on personal and customer vehicles, and so much other stuff I honestly can't remember it all. I am not a professional welder, nor have I received any formal training or instruction, and being self-taught, with a budget flux machine, I trust my welds and the machine I use to be safe for myself and others. I'd build a bumper with it, I'd weld axle tabs and control arms with it. If I had bender and a way to notch tube, I d buy a tank/regulator and build a cage with it.
It isn't as adjustable as the higher dollar, name brand units having only 4 power settings, but I still trust it. It still has enough power to burn 1/4 plate without hesitation, and I have yet to overload it.
