WARNING!

Arc welding and cutting can be injurious to yourself and others. Take precautions

when welding and cutting.

ELECTRIC SHOCK - Can kill

• Install and ground the unit in accordance with instruction manual.

• Do not touch live electrical parts or electrodes with bare skin, wet gloves or

wet clothing.

• Insulate yourself from work and ground.

• Ensure your working position is safe

ELECTRIC AND MAGNETIC FIELDS - Can be dangerous to health

• Welders having pacemakers should consult their physician before welding.

EMF may interfere with some pacemakers.

• Exposure to EMF may have other health effects which are unknown.

• Welders should use the following procedures to minimize exposure to

EMF:

○ Route the electrode and work cables together on the same side of

your body. Secure them with tape when possible. Do not place your

body between the torch and work cables. Never coil the torch or

work cable around your body. Keep welding power source and

cables as far away from your body as possible.

○ Connect the work cable to the workpiece as close as possible to the

area being welded.

FUMES AND GASES - Can be dangerous to health

• Keep your head out of the fumes.

• Use ventilation, extraction at the arc, or both, to take fumes and gases

away from your breathing zone and the general area.

ARC RAYS - Can injure eyes and burn skin

• Protect your eyes and body. Use the correct welding screen and filter lens

and wear protective clothing.

• Protect bystanders with suitable screens or curtains.

NOISE - Excessive noise can damage hearing

Protect your ears. Use earmuffs or other hearing protection.
