These plans are for a DC arc welder to be fitted permanently in a car.
When you need to do welding in the field, a DC welder is generally the choice to use. This welder rig would be fitted beneath the hood of a passenger car. At 200 amps, this welder would be powerful enough to handle electrodes up to3/16- in. diameter.
The welder is completely powered by the engine of the car in which it is installed, and can be taken anywhere that an automobile can be driven.
The main component of the welder is a war-surplus Delco Remy P-l aircraft generator that is rated at 24 v. and 200 amp. at 2500 to 4000 r.p.m.
