ELECTRIC SHOCK CAN KILL
WARNING
- ELECTRICAL SHOCK CAN KILL. DO NOT TOUCH LIVE ELECTRICAL PARTS AND/OR USE IN DAMP
LOCATIONS.
1)
The electrode and work (ground) circuit is electrically
“HOT”
whenever the welding equipment is on. Do not
touch these electrically live parts with your bare skin or wet/damp clothing. Wear dry, hole-free gloves. Incorrectly installed or
improperly grounded equipment is a hazard.
2)
Insulate yourself from work and ground using dry insulating mats or covers big enough to prevent any physical contact with the
work or ground.
3)
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; or when there is a high risk of unavoidable or accidental contact with the workpiece or ground. For these
conditions, use the following equipment in order presented: 1) a semi-automatic DC constant voltage, 2) a DC manual (stick) welder
or 3) an AC welder with reduced open-circuit voltage. In most situations, use of a DC, constant voltage wire welder is recommended
and do not work alone!
4)
Disconnect input power or stop engine before installing or servicing this equipment. Lockout/tag out input power according to
OSHA 29 CFR 1910.147 (see Safety Standards).
5)
Properly install ground and operate this equipment
according to its Owner’s Manual and national, state/provincial and local codes.
6)
Always verify the supply ground. Make sure that input power cord ground wire is properly connected to ground terminal in
disconnect box or that cord plug is connected to a properly grounded receptacle outlet.
7)
Keep cords dry, free of oil and grease and protected from hot metal and sparks.
8)
Frequently inspect input power cord for damage or bare wiring. Replace cord immediately if damaged. Bare wiring can kill.
9)
Turn off all equipment when not in use.
10)
Do not use worn, damaged, undersized or poorly spliced cables. It is illegal to use electrical tape to repair torch power cable or
ground cable that has damaged outer insulation. The cable must be replaced.
11)
Do not drape cables over your body.
12)
Do not touch electrode if you are in contact with the work, ground or another electrode from a different machine.
13)
Do not touch electrode holders connected to two welding machines at the same time since double open circuit voltage will be
present.
14)
Use only well-maintained equipment. Repair or replace damaged parts at once. Maintain unit according to manual.
15)
Wear a safety harness if working above floor level.
16)
Keep all panels and covers securely in place.
17)
Clamp work cable with good metal-to-metal contact to workpiece or worktable as near the weld as practical.
18)
Do not connect more than one electrode or work cable to any single weld output terminal. Disconnect cable for process when not
in use.
ARC RAYS HAZARDS
WARNING
–
A WELDING ARC EMITS ULTRAVIOLET (UV) AND OTHER RADIATION AND CAN CAUSE
SERIOUS INJURY TO UNPROTECTED SKIN AND EYES.
1)
Use a shield with the proper filter and cover plates to protect your eyes from sparks and the
rays of the arc when welding or observing open arc welding. Headshield and filter lens should
conform to ANSI Z87. I standards.
2)
Use suitable clothing made from durable flame-resistant material to protect your skin and that
of your helpers from the arc rays.
3)
Protect other nearby personnel with suitable, non-flammable screening and/or warn them not
to watch the arc nor expose themselves to the arc rays or to hot spatter or metal.
