To prevent fire, explosion and rupture, ensure to follow the instructions below:
• Remove all flammables within 33 ft (10 m) of the welding arc so that sparks and
spatter do not strike flammable materials. If this is not possible, tightly cover them with
noncombustible covers.
• When welding on a ceiling, floor, bulkhead or partition, remove all flammable materials
in hidden places.
• Tighten all cable connections and insulate them.
Loose connection in the cable and current path of the base metal such as steel frame
may cause electric shocks and fire hazards from energization.
• Connect power cable for base metal as close to the welding area as possible.
• Do not weld on gas pipe and closed containers such as tanks or drums.
• Performing arc welding on flammable object such as fuel tank may cause explosion.
Furthermore, welding on closed container such as tanks and pipes may cause burst.
• Watch for fire and keep a fire extinguisher near the welding area.
• Periodically blow the parts of welding power source with dry compressed air to remove
dust.
Powder dust accumulating inside may cause insulation deterioration, resulting in
electric shock or fire.
• Do not place hot base metal after welding near flammable materials.
Spatter and hot base metal after welding can cause fire.
• Do not place the welding power source near combustible materials or flammable gas.
• Do not place the welding torch near the wire feeder or the frame of wire reel stand.
• When there is an electrical connection between a workpiece and the frame of wire
feeder or the wire reel stand, arc may be generated and cause damage by a fire if the
wire contacts the frame or the workpiece.
