Materials/tools.
Auxiliary generator (24 vdc)
Control unit from a welder or similar control
Welder's helmet and gloves
Welding rod, coat hangers, or barbed wire
Heavy gauge cable (2.0 gauge or larger)
Vise grips or clamps
Fuel line
c.
Personnel/time required.

d.
Procedural Steps.
(1)
Remove auxiliary generator from M88 recovery vehicle and place close to area to be welded. Connect
heavy gauge cables to ( + ) and ( ) output posts. Also connect control to ( + ) and ( -) output posts.
Tighten terminals securely.
(2)
Connect negative ( ) cable to generator frame with clamp close to area to be welded. Connect welding
rod to positive ( + ) cable with vise grips. Insulate vise grips with gloves, rags, or several layers of dry
paper.
WARNING
Use welder's helmet to protect eyes and face from arc. Do not touch exposed cable or vise grips
with bare hands; metal gets very hot. Do not perform this task in rain or on wet ground because of
electrical shock hazard. Disconnect batteries on generator being repaired prior to welding.
(3)
Start auxiliary generator, strike arc, and weld. Set control unit for amperage level required by the
thickness of the metal.
(4)
Record the BDAR action taken. When the mission is completed, as soon as practicable, repair
generator using standard maintenance procedures.
(5)
Other options: Use uncontrolled amperage.
B-5. Uncontrolled Amperage . Battlefield repairs requiring welding can be accomplished by using auxiliary generator
(Little Joe) from M88 recovery vehicle or a generator if a regular welder is not available. Welding will be difficult without
amperage control.
