5. SAFETY
The above signals mean warning! Notice! Running parts and getting an electric shock or thermal parts will take
damage for your body or others. The corresponding notices are as follows. It is quite a safe operation after taking
several necessary protection measures. .
Arc Welding Damage
•
The following signals and word explanations are to some damages for your body or others happening on the
welding operation. While seeing these, please remind of yourself or others to be dangerous.
•
Only ones who are trained professionally can install, debug, operate, maintain and repair the equipment.
•
During the operation, non-concerned people should be lift, especially for children.
•
After shut off the machine power, please maintain and examine the equipment according to §5 because of the
DC voltage existing in the electrolytic capacitors.
ELECTRIC SHOCK CAN KILL.
•
Never touch electrical parts.
•
Wear dry, hole-free gloves and clothes to insulate yourself.
•
Insulate yourself from workpiece and ground using dry insulation. Make certain the insulation is large enough to
cover your full area of physical contact with workpiece and ground.
•
Take carefully when using the equipment in small place, falling-off and wet circumstance.
•
Never close the machine power before installation and adjustment.
•
Ensure to install the equipment correctly and ground the work or metal to be welded to a good electrical (earth)
ground according to the operation manual.
•
The electrode and work (or ground) circuits are electrically "hot" when the welder is on. Do not touch these "hot"
parts with your bare skin or wet clothing. Wear dry, hole-free gloves to insulate hands.
•
In semiautomatic or automatic wire welding, the electrode, electrode reel, welding head, nozzle or
semiautomatic welding gun are also electrically "hot".
•
Always be sure the work cable makes a good electrical connection with the metal being welded. The connection
should be as close as possible to the area being welded.
•
Maintain the electrode holder, work clamp, welding cable and welding machine in good, safe operating
condition. Replace damaged insulation.
•
Never dip the electrode in water for cooling.

Solution
Keep out air
Change new electrode.
Adjust another angle to weld
Use the short-arc operation
Change the position of earth cable
Change welding direction
Reduce the welding current output
Reduce the duty cycle (work intervally)
