Procedural Steps (Cont):
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 vehicle using standard maintenance procedures.
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.
q Possible degraded armor protection
q 2 soldiers
q 1-3 hours
Auxiliary generator (24 vDC)
Heavy gauge cable (2.0 gauge minimum)
Vise grips or clamps
Welder helmet and gloves
Welding rod, coat hangers, or barbed wire
q Weld using the vehicle battery power
1. Remove auxiliary generator from M88 recovery vehicle and place close to area to be
welded. Connect heavy gauge cables (+) and (-) output posts and tighten securely.
2. Connect negative (-) cable to vehicle hull with clamp close to area to be welded.
Connect welding rod to positive (+) cable with vise grip and insulate area against heat
with gloves, rags, or several layers of dry paper.
