READ INSTRUCTIONS

Thoroughly read and understand this manual before using the welder. Save for future refer-
ence.

ELECTRIC SHOCK CAN KILL!

Improper use of an electric welder can cause electric shock, injury and death! Read all pre-
cautions described in the Welder Manual to reduce the possibility of electric shock.
Disconnect welder from power supply before assembly, disassembly or maintenance of the
torch, contact tip and when installing or removing nozzles.
Always wear dry, protective clothing and leather welding gloves and insulated footwear.
Use suitable clothing made from durableflame-resistant material to protect your skin.
If other persons or pets are in the area of welding, use welding screens to protect bystand-
ers from sparks.
Always operate the welder in a clean, dry, well ventilated area. Do not operate the welder in
humid, wet, rainy or poorly ventilatedareas.
The electrode and work (or ground) circuits are electrically "hot" when the welder is on. Do
not allow these "hot" parts to come in contact with your bare skin or wet clothing.
Separate yourself from the welding circuit by using insulating mats to prevent contact from
the work surface.
Be sure that the work piece is properly supported and grounded prior to beginning an elec-
tric welding operation.
Always attach the ground clamp to the piece to be welded and as close to the weld area as
possible. This will give the least resistance and best weld.
WELDING SPARKS CAN CAUSE FIRE OR EXPLOSION!
Electric welding produces sparks which can be discharged considerable distances at high
velocity igniting flammable or exploding vapors and materials.
Do not operate electric arc welder in areas where flammable or explosive vapors are pres-
ent.
Do not use near combustible surfaces. Remove all flammable items within 35 feet of the
welding area.
Always keep a fire extinguisher nearby while welding.
Use welding blankets to protect painted and or flammable surfaces; rubber weather-
stripping, dash boards, engines, etc.
Ensure power supply has properly rated wiring to handle power usage.
ELECTROMAGNETIC FIELDS CAN BE A HEALTH HAZARD!
The electromagnetic field that is generated during arc welding may interfere with various
electrical and electronic devices such as cardiac pacemakers. Anyone using such devices
should consult with their physician prior to performing any electric welding operations.
Exposure to electromagnetic fields while welding may have other health effects which are
not known.
