Auto motor powered portable arc welder vintage diy plans

car motor powered portable arc welderAn car mounted arc welder powered by the car’s motor!

SMALL ENOUGH to be hidden beneath
the hood of a passenger car, yet powerful
enough to handle electrodes up to 3/16-
in. dia., this 200-amp. welder is 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. Since this generator
has a counterclockwise rotation, it must be
turned end for end and driven from the
commutator end when rotated by a car engine.
This requires that the floating shaft,
which drives the free-turning armature, be
removed from the generator and modified.
