4-6. Safety Information For Connecting To Weld Output Terminals
UNEXPECTED WELD OUTPUT can cause injury or fire.
Both weld outputs can be live (ON) when Welder Selector switch is in Welder A/Welder B position and engine is running.
Disconnect or insulate any unused cables.
Know where cables are located BEFORE starting engine.
ELECTRIC SHOCK can kill; ARCING can burn skin or damage electrical connections.
Stop engine before making any weld output connections.
Do not connect welding output of different polarities to the same structure.
See ANSI Z49.1 and OSHA Title 29, Chapter XVII, Part 1910, Subpart Q (addresses at beginning of manual).
When welding on the same workpiece, all connections to the workpiece must be of the same polarity.
Do not handle or come in contact with two live electrodes at the same time.
ELECTRIC SHOCK can kill; TWO TIMES NORMAL OPEN-CIRCUIT VOLTS can exist between electrode holders of opposite polarity.
Do not touch electrode holders of opposite polarity at the same time.
Separate electrode holders of opposite polarity to prevent contact.
Consult ANSI Z49.1 for common grounding safe practices.
