5-6. Safety Information For Connecting To Weld Output Terminals

Y UNEXPECTED WELD OUTPUT can cause injury or fire.

D Both weld outputs can be live (ON) when Welder Selector switch is in Welder A/Welder B position and engine is running.
D Disconnect or insulate any unused cables.
D Know where cables are located BEFORE starting engine.

Y ELECTRIC SHOCK can kill; ARCING can burn skin or damage electrical connections.

D Stop engine before making any weld output connections.
D Do not connect welding output of different polarities to the same structure.
D See ANSI Z49.1 and OSHA Title 29, Chapter XVII, Part 1910, Subpart Q (addresses at beginning of manual).
D When welding on the same workpiece, all connections to the workpiece must be of the same polarity.
D Do not handle or come in contact with two live electrodes at the same time.

Y ELECTRIC SHOCK can kill; TWO TIMES NORMAL OPEN-CIRCUIT VOLTS can exist between electrode holders of opposite polarity.

D Do not touch electrode holders of opposite polarity at the same time.
D Separate electrode holders of opposite polarity to prevent contact.
D Consult ANSI Z49.1 for common grounding safe practices.
