SAFETY INSTRUCTIONS
May 06, 2020 Page 5 User Manual No: OM-101A EN
SECTION 1 –SAFETY INSTRUCTIONS: Read Before Using this Product
DANGER! –Protect yourself and others around you from possible serious injury or death.
1) Read, follow and understand this User Manual before installing, operating or servicing this Prod-
uct. 2) Pacemaker wearers keep away until consulting your doctor. 3) Have all installation, opera-
tion, maintenance and repair work performed only by Suitably Trained and Qualified Tradesperson.
4) Keep children away. 5) Do not lose these instructions.
6) When shipped, ownership is passes to the purchaser upon receipt from the transportation company. Accordingly,
claims for component damaged in shipment must be made by the purchaser against the transportation company at
the time the shipment is received.
“NOTE:” Provides information regarding operating recommendations for this Product.
Product and processes can cause serious injury or death, or damage to other equipment or property, if the operator does
not strictly observe all safety instructions and take precautionary actions.
Anyone not extensively trained in welding and cutting practices should not attempt to weld or cut metal.
Safe practices are outlined in American National Standard Z49.1 entitled: SAFETY IN WELDING AND CUTTING. This pub-
lication and other guides to what you should learn before using this product are listed at the end of these safety instruc-
tions.
1.01 Arc Welding Hazard Symbols
ELECTRIC SHOCK can kill
Touching live electrical parts can cause fatal
shocks or severe burns. The electrode and
work circuit are electrically live whenever
the output is on. DO NOT WORK ALONE!
The input power circuit and Power Source
internal circuits are also electrically live
when power is on. In semiautomatic or au-
tomatic wire welding, the wire, wire reel,
drive roll housing, and all metal parts touch-
ing the welding wire are electrically live. In-
correctly installed or improperly grounded
welding equipment is a hazard.
•Do not touch live electrical parts.
•Beware of electric shock from wiring.
•Keep all panels and covers securely in place.
•Wear dry, hole-free insulating gloves and body protection.
•Insulate yourself from work and ground using dry insulating mats or
covers big enough to prevent any physical contact with the work or
ground.
•Additional safety precautions are required when any of the following
electrically hazardous conditions are present:
–In damp locations or while wearing wet clothing;
–On metal structures such as floors, gratings or scaffolds;
–When in cramped positions such as sitting, kneeling or lying;
–When there is a high risk of unavoidable or accidental contact with
the workpiece or ground.
For these conditions, use the following equipment:
1) A semiautomatic DC constant voltage (wire) welder, or
2) A DC manual (stick) welder. In most situations a DC welder is rec-
ommended.
•Disconnect input power or stop engine before installing or servicing
this Product. Lockout/Tagout input power according to OSHA 29 CFR
1910.147.
•Properly install and ground this Power Source according to its User
Manual and national, state, and local codes.
•Use only well-maintained equipment. Repair or replace damaged parts
at once.
•Do not wrap cables around your body.
•Always verify the Input Power Cord ground −check and be sure that
Input Power Cord ground wire is properly connected to ground termi-
nal in disconnect box or that Input Power Cord plug is connected to a
properly grounded receptacle outlet.
•When making input connections, attach proper grounding conductor
first. DOUBLE - CHECK ALL CONNECTIONS.
•Keep all electrical Power Cords dry, free of oil and grease, and pro-
tected from hot metal, sparks and sharp metal edges.
•Frequently inspect Input Power Cord and ground conductor for dam-
age or bare wiring. Replace immediately if damage, bare wiring can
kill.
•Turn off all equipment when not in use. Disconnect power to equip-
ment if it will be left unattended or out of service.
•Use fully insulated Torch. Never dip Torch in water to cool it or lay it
down on the ground or the work surface. Do not touch Torches con-
nected to two Power Sources at the same time or touch other people
with the Torch or electrode.
•Do not use worn, damaged, undersized, repaired or poorly spliced ca-
bles.
•Ground the work piece to a good electrical (earth) ground.
•Do not touch electrode while in contact with the work (ground) circuit.
•In confined spaces or damp locations, do not use a welder with AC
output unless it is equipped with a voltage reducer. Use equipment
with DC output.
•Wear a safety harness to prevent falling if working above floor level.
•Do not touch electrode holders connected to two Power Sources at the
same time as double open-circuit voltage will be present.
•Insulate work clamp when not connected to workpiece to prevent con-
tact with any metal object.
•Do not connect more than one electrode or work cable to any single
weld output terminal. Disconnect cable for process not in use.
•Use ground-fault circuit interrupter (GFCI) protection when operating
auxiliary equipment in damp or wet locations.
FLYING METAL or DIRT can injure eyes
Welding, chipping, wire brushing, and grind-
ing cause sparks and flying metal.
•Welding slag can be thrown off welds as they
cool down.
•Wear approved safety glasses with side shields even under your weld-
ing helmet.
HOT PARTS can burn
Nozzles, contact tips, gas diffuser welded
parts, cut metal, or ground clamp can cause
burn bare skin when hot.
•Don’t touch hot parts with bare skin.
•To handle hot parts, use proper tools and/or wear heavy, insulated
welding gloves and clothing to prevent burns.
Disconnect
