SECTION 1: SAFETY PRECAUTIONS
WARNING
SERIOUS INJURY OR DEATH may result if welding and cutting equipment is not properly installed, used, and maintained. Misuse of this equipment and other unsafe practices can be hazardous. The operator, supervisor, and helper must read and understand
the following safety warnings and instructions before installing or using any welding
or cutting equipment, and be aware of the dangers of the welding or cutting process.
Training and proper supervision are important for a safe work place. Keep these instructions for future use. Additional recommended safety and operating information is
referenced in each section.
WARNING
This product contains chemicals, including lead, known to the State of California to
cause birth defects and other reproductive harm. Wash hands after handling.
ELECTRIC SHOCK CAN CAUSE INJURY OR DEATH
Install and maintain equipment in accordance with the National Electrical Code
(NFPA 70) and local codes. Do not service or repair equipment with power on.
Do not operate equipment with protective insulators or covers removed.
Service or repair to equipment must be done by qualified and/or trained
personnel only.
Do not contact electrically live parts. Always wear dry welding gloves that are in good
condition. Aluminized, protective clothing can become part of the electrical path. Keep oxygen
cylinders, chains, wires, ropes, cranes, and hoists away from any part of the electrical path.
All ground connections must be checked periodically to determine if they are mechanically
strong, and electrically adequate for the required current. When engaged in AC welding/
cutting under wet conditions or where perspiration is a factor, the use of automatic controls
for reducing the no load voltage is recommended to reduce shock hazards. Accidental contact
must be prevented when using open circuit voltage exceeding 80 volts AC, or 100 volts DC by
adequate insulation or other means. When welding is to be suspended for any length of time,
