Safety instructions
WARNING
FLYING SPARKS and HOT METAL
can cause injury.
Chipping and grinding cause flying metal. As welds cool, they can throw off slag.
1. Wear approved face shield or safety goggles. Side shields recommended.
2. Wear proper body protection to protect skin.
WARNING
CYLINDERS can explode if damaged.
Shielding gas cylinders contain gas under high pressure. If damaged, a cylinder can
explode. Since gas cylinders are normally part of the welding process, be sure to treat
them carefully.
1. Protect compressed gas cylinders from excessive heat, mechanical shocks, and arcs.
2. Install and secure cylinders in an upright position by chaining them to a stationary support
or equipment cylinder rack to prevent falling or tipping.
3. Keep cylinders away from any welding or other electrical circuits.
4. Never allow a welding electrode to touch any cylinder.
5. Use only correct shielding gas cylinders, regulators, hoses, and fittings designed for the
specific application; maintain them and associated parts in good condition.
6. Turn face away from valve outlet when opening cylinder valve.
7. Keep protective cap in place over valve except when cylinder is in use or connected
for use.
8. Read and follow instructions on compressed gas cylinders, associated equipment.
WARNING
ENGINE FUEL can cause fire or explosion.
Engine fuel is highly flammable.
1. Stop engine before checking or adding fuel.
2. Do not add fuel while smoking or if unit is near any sparks or open flames.
3. Allow engine to cool before fuelling. If possible,check and add fuel to cold engine before
beginning job.
4. Do not overfill tank — allow room for fuel to expand.
5. Do not spill fuel. If fuelling is spilled, clean up before starting engine.
6. Be aware that welding on a ceiling, floor, bulkhead, or partition can cause fire on the
hidden side.
7. Do not weld on closed containers such as tanks or drums.
8. Connect work cable to the work as close to the welding area as practical to prevent
welding current from travelling long, possibly unknown paths and causing electric
shock and fire hazards.
9. Do not use welder to thaw frozen pipes.
10. Remove stick electrode from holder or cut off welding wire at contact tip when not
in use.

WARNING
SPARKS can cause battery gases to explode;
BATTERY ACID can burn eyes and skin.
Batteries contain acid and generate explosive gases.
1. Always wear a face shield when working on a battery.
2. Stop engine before disconnecting or connecting battery cables.
3. Do not allow tools to cause sparks when working on a battery.
4. Do not use welder to charge batteries or jump start vehicles.
5. Observe correct polarity (+ and –) on batteries.
WARNING
STEAM AND PRESSURIZED HOT COOLANT
can burn face, eyes, and skin.
The coolant in the radiator can be very hot and under pressure.
1. Do not remove radiator cap when engine is hot. Allow engine to cool.
2. Wear gloves and put a rag over cap area when removing cap.
3. Allow pressure to escape before completely removing cap.
NOTE
To reduce magnetic fields in the workplace, use the following procedures.
1. Keep cables close together by twisting or taping them.
2. Arrange cables to one side and away from the operator.
3. Do not coil or drape cable around the body.
4. Keep welding Power Source and cables as far away from body as practical.
5. The people with heart-pacemaker should be away from the welding area.
1.2 Effects Of Low Frequency Electric and Magnetic Fields
Electric current flowing through any conductor causes localized Electric and Magnetic
Fields (EMF). The discuss on the effect of EMF is ongoing all the world. Up to now, no
material evidences show that EMF may have effects on health. However, the research
on damage of EMF is still ongoing. Before any conslusion, we should minimize exposure
to EMF as few as possible.
WARNING
MOVING PARTS can cause injury.
Moving parts, such as fans, rotors, and belts can cut fingers and hands and catch loose
clothing.
1. Keep all doors, panels, covers, and guards closed and securely in place.
2. Stop engine before installing or connecting unit.
3. Have only qualified people remove guards or covers for maintenance and troubleshooting
as necessary.
4. To prevent accidental starting during servicing, disconnect negative (-) battery cable
from battery.
5. Keep hands, hair, loose clothing, and tools away from moving parts.
6. Reinstall panels or guards and close doors when servicing is finished and before
starting engine.
