1. Safety Symbol Definitions

DANGER! −Indicates a hazardous situation which, if not

avoided, will result in death or serious injury. The possible

hazards are shown in the adjoining symbols or explained

in the text.

Beware of electric shock from welding electrode or wiring.

Touching the electrode while in contact with the work or

ground can cause electric shock. Always wear dry

gloves. Keep all panels and covers closed.

Indicates a hazardous situation which, if not avoided,

could result in death or serious injury. The possible ha-

zards are shown in the adjoining symbols or explained in

the text.

Hot parts can cause burns. Welding makes parts very hot

−let them cool before touching.

NOTICE Indicates statements not related to personal injury.

Indicates special instructions.

Wear safety glasses with side shields.

Proposition 65 Warnings

Welding or cutting equipment produces fumes or gases which contain chemicals known to the State of California to cause birth defects and, in

some cases, cancer. (California Health & Safety Code Section 25249.5 et seq.)

This product contains chemicals, including lead, known to the state of California to cause cancer, birth defects, or other reproductive harm.

Wash hands after use.

Duty Cycle is percentage of 10 min-

utes that unit can weld at rated load

without overheating.

NOTICE −Exceeding duty cycle

can damage unit and void warranty.
