ok, i know theres probably something like this on here already, if there is please someone point me to it. i want to get a welding set up so i can fab my own tube bumpers and rock sliders and the like. i want to be able to weld without breaking the bank either. theres some at harbor freight mostly right around 150 electric arc welders a few of them you can select either 120 or 240. will these work out for me? there is also an oxy set up for 100 bucks minus the tanks, i heard that the gases get real expensive real quick. any input would be really helpful thanks guys.
