Incorrect Installation

minal. Slide weld cable terminal onto weld output terminal and secure with nut so that weld cable terminal is tight against copper bar. Do not place anything between weld cable terminal and copper bar. Make

sure that the surfaces of the weld cable terminal and copper bar are clean.

4-6. Connecting To Weld Output Terminals

WARNING

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

• Do not touch live electrical parts.
•	Turn Off polyweld system by pressing Power Off push button 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 Positive or Negative weld output terminal is jumper linked to the Frame Connection terminal and the work cable is con-
	nected to the Common Work Connection stud on the machine base, do not connect a cable between the remaining weld output
•	terminal and the work.
•	Remove jumper link from any module where work and electrode connections are made directly to the Positive and Negative
•	output studs.
•	Do not handle or come in contact with two live electrodes at the same time.
•	Connect all paralleled modules for the same polarity.

ELECTRIC SHOCK can kill; TWO TIMES NORMAL OPEN-CIRCUIT VOLTS exist between elec- trode 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.
