SAFETY INSTRUCTION
BUG-O / ALL-TIME arc welding and cutting equipment is designed and built with safety in mind. However,
correct installation and operation are the most important measures to ensure your safety. Installation,
operation and maintenances before reading through this manual and corresponding safety regulations
included in this is manual is strongly recommended. Most importantly, customers should consider proper
installation, and maintenance before operation.
1. Beware of electric shock
A. During the welding operation of the Equipment, the circuit formed between the covered electrode and
the work piece (or the ground) is charged. Exposed skin or wet or damp clothing may cause harm if you
make contact with these charged parts. Workers should put on dry gloves with segregated fingers to
obtain good insulation.
B. Use dry and insulated protection to insure that you are insulated from the work-piece and the ground.
Moreover, the insulation should be enough to isolate you from the work piece or the ground. If the
welding operation must be conducted in the circumstance that may cause electric shocks (in moist
places or wearing wet or damp clothes; on the metal structure such as the floor, the palisade and
the scaffold; when the body is not stretching such as sitting, kneeling or reclining, and the body will
inevitably have contact with the work piece or the ground in these condition), the operation should be
conducted according to the security specification and the following equipment should be utilized:
• Semi-automatic DC constant-voltage (wire feeding machine) welder
• DC manual metal arc welder
• AC welder with anti-electric function
C. In the semi-automatic and automatic welding process, many parts are charged, such as the wire, the
wire-feeding wheel, the welding head, the nozzle and the semi-automatic welding torch.
D. Ensure that the electric cable is firmly connected with the work piece metal. Moreover, the connection
should be as close as possible to the welding zone.
E. The work piece to be welded should be grounded well.
F. Ensure that the electrode holder, the work piece gripper and the welder are operated in good conditions.
Damaged insulation parts should be replaced.
G. Immersion of the electrode into the water to cool is forbidden.
H. Touching two wire holders of different welders simultaneously is forbidden for the reason that the voltage
between them may be the sum of their open circuit voltages.
I. In the course of suspension work, the worker should use safety equipment to avoid falling.
2. Beware of the arc light
A. When you observe the arc light during the welding process, you should wear a mask with welding -rated
glass. Appropriate flame-retardant material should be used to protect other persons and warn them not
to observe the welding arc light or to keep away from the arc light, the spatter or hot work piece.
B. The mask with black glass and cover plate is to protect your eyes from burning by the spark or arc light.
The mask and black glass must meet the requirements listed in the standard ANSIZ87.1. Wear clothes
made of refractory materials to protect skin from burning by the spark or the arc light.
