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

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.
2 Read Owner’s Manual and
inside labels for connection
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.
