Brief word about welders, electric arc welders (stick welders) have differant available power outputs to the welding leads. Some are Alternating Current (AC), others are Direct Current (DC), some welders have both outputs that can be changed by where you plug in the leads or turn the switch. If you ever use the welder for a battery charger IT HAS TO BE DC CAPABLE!!! , make sure you know what the leads are plugged into. Ground clamp needs to be plugged into the ground (negative) at the welder and the stinger is Positive. Operators of welders may change these back and forth in DC welding depending on what type of rod they are welding with. Some welding rods are run with the stinger negative and the ground clamp positive. "DC Reverse Polarity" is a common welding term and refers exactly to what I've already described, ground lead is negative, stinger that holds the welding rod is positive. This is what you want. Be sure of this before you try to make a welder work as an emergency battery charger. *****DISCLAIMER! *****Emergency Use only***** HIGH RISK of this not working out well. DO NOY TRY THIS AT HOME!
