  • Page 8 Safety Warnings, Dangers, Cautions and Instructions DANGER! Welding and cutting operations pose serious inhalation hazards. Some of these hazards are immediate while others are cumulative in their effect. Do not weld in enclosed spaces or in areas without adequate ventilation. Fumes and gases released in the welding and cutting operations can be toxic.
  • Page 9 Safety Warnings, Dangers, Cautions and Instructions CAUTION! Trip Hazards exist around welders. Cords, cables, welding leads and hoses pose a trip hazard. Be aware of their location and inform others of their location. Tape and se- cure them so they will stay out of high traffic areas. CAUTION! Welded metal can stay hot long after welding is completed.

    Duty Cycle Duty Cycle Information Duty Cycle is simply the amount of time out of a 10 minute period in which the unit can operate. For example, this unit has a duty cycle of 25%. This means that the unit can be welding for 2.5 minutes out of 10 minutes at 140 Amps (MIG, TIG; 80A for Stick) maximum output. The 2.5 minutes of welding time may be continuously, or intermittently during the 10 minute period of time.
