Warning! Watch Out! There are

possible hazards as shown by the

symbols.

1 Electric shock from welding

electrode or wiring can kill.

1.1 Wear dry insulating gloves.

Do not touch electrode with

bare hand. Do not wear wet or

damaged gloves.

1.2 Protect yourself from electric

shock by insulating yourself

from work and ground.

1.3 Disconnect input plug or

power before working on

machine.

2 Breathing welding fumes can

be hazardous to your health.

2.1 Keep your head out of the

fumes.

2.2 Use forced ventilation or local

exhaust to remove the fumes.

2.3 Use ventilating fan to remove

fumes.

3 Welding sparks can cause

explosion or fire.

3.1 Keep flammables away from

welding. Do not weld near

flammables.

3.2 Welding sparks can cause

fires. Have a fire extinguisher

nearby, and have a

watchperson ready to use it.

3.3 Do not weld on drums or any

closed containers.

4 Arc rays can burn eyes and

injure skin.

4.1 Wear hat and safety glasses.

Use ear protection and button

shirt collar. Use welding

helmet with correct shade of

filter. Wear complete body

Warning! Watch Out! There are

possible hazards as shown by the

symbols.

Electric shock from wiring can kill.

Disconnect input plug or power

before working on machine.

Read the Owner’s Manual before

working on this machine.

1 Consult rating label for input

power requirements, and

check power available at the

job site −they must match.

points and procedures.

3 Move jumper links as shown

on inside label to match

voltage at job site.

4 Having a loop of extra length,

connect grounding conductor

first.

5 Connect line input conductors

as shown on inside label −

double-check all connections,

jumper link positions, and

input voltage before applying

power.
