SECTION 9 − TROUBLESHOOTING

9-1. GENERAL

It is assumed that proper installation has been made, according to Section 4 of this manual, the operator is fa- miliar with the function of controls, the welding generator was functioning properly, and the trouble is not related to the welding process.

9-2. BOOSTER BATTERY JUMP STARTING

If it is necessary to jump start this unit, use the following safety precautions and the step-by-step procedures in order of appearance.

WARNING: BATTERY GASES OR A DAM- AGED BATTERY can explode thereby shat- tering the battery; BATTERY ACID can burn eyes, skin, destroy clothing, and damage other material; MOVING PARTS AND IM- PROPER CONNECTIONS can cause serious personal injury and damage equipment.

Keep sparks, flames, cigarettes, and other ig- nition sources away from battery.

Ensure that all personnel are a safe distance from batteries and clear of moving parts while starting.

Do not jump start a frozen or completely dis- charged battery.

Do not jump start a battery which has loose terminals or one having evidence of damage such as a cracked case or cover.

Be sure that vent caps are tight and level on both batteries and cover both batteries with a damp cloth.

Wear correct eye and body protection, and remove all metal jewelry.

Keep jumper cables clear of moving parts.

Ensure that both batteries are of the same voltage.

Do not jump start a trailer mounted welding generator with the towing vehicle battery un- less the trailer is completely disconnected from the towing vehicle.

Do not jump start a vehicle mounted welding generator from the vehicle battery.

If booster battery is installed in vehicle, do not allow vehicle to make contact with welding generator case or frame.

Do not jump start by applying power to weld output receptacles or terminals.

Do not allow jumper cables to contact any other metal while attaching or removing ca- bles.

1.Use properly insulated jumper cables of ade- quate size.

2.Connect ends of one cable to positive (+) termi- nals of each battery.

3.Connect one end of other cable to negative (−) terminal of booster battery.

4.Connect remaining end of cable to welding gen- erator engine block at least 18 inches (457 mm) from battery (do not connect to welding generator case, frame, or equipment grounding terminal as damage to equipment can result).

5.Wait at least one minute after connecting cables before starting engine.
