Repair To DC Welding Generator FARM SHOP Repairs 26-5-39 Donald Winkler, North Platte, Neb.: "Our oldest son bought a used arc welder from the maintenance department of a local factory. It was a large D.C. welding generator driven by a 220-volt, 3-phase A.C. motor. They sold it cheap because it didn't work properly. The problem was that the company had crossed the 220-volt input wires, which caused the armature to run backward. As a result it wouldn't excite the generator fields. They tried using a car battery to excite the generator. This caused the generator to produce a D.C. welding current, but because the armature was rotating in the wrong direction, the commutator brushes arced terribly.
"Our son, John, pulled the A.C. motor armature off the common shaft that it shared with the D.C. armature. Then he coupled the shaft to a 4-cyl. Jeep engine and mounted everything on a 4-wheel trailer. The result is a portable gas-driven, D.C. welder. It has a lot of power and runs a strong, smooth bead."
