2 Safety
Only qualified persons should install, operate, maintain, and repair this unit.
During operation, keep everybody, especially children, away.
Electrical Hazards
Electric shock from welding can kill or cause severe burns. The electrode and work
circuit is electrically energized whenever the output is on. The input power circuit
and unit internal circuits are also electrically energized when the mains power is on.
When MIG welding, the wire, drive rolls, and all other metal parts touching the wire
are electrically energized. Incorrectly installed or improperly grounded equipment
presents a shock hazard.
Read the instruction manual before installing, operating, or servicing the unit.
Have all installation, operation, maintenance, and repair work performed only
by qualified people.
Do not touch live electrical parts.
Wear dry, insulating in good condition and protective clothing.
Insulate yourself from the workpiece and ground by wearing rubber-soled
shoes or standing on a dry insulated mat or platform.
Use fully insulated electrode holders. Never dip the holder in water to cool it
or lay it on conductive surfaces or the work surface. Do not touch holders
connected to two welding machines at the same time or touch other people
with the holder or electrode.
Do not use worn, damaged, undersized, or poorly spliced cables, welding gun
cables, and torch cables. Make sure all connections are tight, clean, and dry.
Do not wrap cables carrying welding current around your body.
In confined spaces or in electrically hazardous locations due to water or
perspiration, do not use a welder with AC output unless it is equipped with a
voltage reducer and remote output control. Use equipment with DC output.
Turn off all equipment when not in use. Disconnect the power to equipment if
it will be left unattended or out of service.
Wear a safety harness to prevent falling in a potentially hazardous area.
Keep all covers secured in place.
Many welding processes produce fumes and gases, which may be harmful to your
health.
Keep your head out of the fumes. Do not breathe the fumes.
If inside, use ventilation or an exhaust at the arc to remove welding fumes
and gases.
