    SAFETY §1 Safety Notice: The instructions are for reference only. The manufacturer reserves the right to explain the differences between the description and the product due to product changes and upgrades! Welding and cutting equipment can be dangerous to both the operator and people in or near the surrounding working area, if the equipment is not correctly operated.
  • Page 4 SAFETY ELECTRIC SHOCK CAN KILL. Touching live electrical parts can cause fatal shocks or severe burns. The electrode and work circuit is electrically live whenever the output is on. The input power circuit and internal machine circuits are also live when power is on. In MIG/MAG welding, the wire, drive rollers, wire feed housing, and all metal parts touching the welding wire are electrically live.
  • Page 5 SAFETY Welding produces fumes and gases. Breathing these fumes and gases can be hazardous to your health.  Do not breathe the smoke and gas generated whilst welding or cutting, keep your head out of the fumes. Use enough ventilation and/or exhaust at the arc to keep fumes and gases away from the breathing zone.
  • Page 6 SAFETY  Do not put your hands near the engine fan. Do not attempt to override the governor or idler by pushing on the throttle control rods while the engine is running. DO NOT add any fuel near an open-flame welding arc or when the engine is running.
