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.

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.
