SECTION 3 – MAKING WELD OUTPUT CONNECTIONS
3-1. Work And Electrode Cable Connections For Single DC or AC Arcs
Y ELECTRIC SHOCK can kill.
Do not touch live electrical parts.
Turn off welding power sources and disconnect input power before making any weld output con-
nections.
See ANSI Z49.1 and OSHA Title 29, Chapter XVII, Part 1910, Subpart Q (addresses at begin-
ning of manual).
Do not handle or come in contact with two live electrodes at the same time.
Y UNDERSIZED WELD CABLES can cause fire.
Work cable or electrode cable must be able to carry the weld output of the individual welding power
source (see Section 2-8).
Do not exceed duty cycle of welding power sources.
To Electrode
Connections For
DC Electrode Positive
Or AC Output
Y High weld output current hazard! Remove all metal jewelry, such as
rings and watches, and be careful with tools near output terminals.
High current can cause severe burns from hot metal if touched to
output terminals and unit is On. ALWAYS turn Off welding power
sources and disconnect input power BEFORE making weld output
connections.
Y If there are any questions regarding
this procedure, contact the factory be-
fore connecting units.

Connections For
DC Electrode
Negative Output
Y Turn Off welding power
source and disconnect input
power before opening ac-
cess door.
For dc electrode positive:
Connect the proper size and num-
ber of weld output cables (see Sec-
tion 2-8) to one of the welding power
source electrode terminals.
Connect the proper size and num-
ber of ground cables to one of the
welding power source work termi-
nals.
For dc electrode negative:
Connect the proper size and num-
ber of weld output cables (see Sec-
tion 2-8) to one of the welding power
source work terminals.
Connect the proper size and num-
ber of ground cables to one of the
welding power source electrode
terminals.
For ac output:
To Electrode
Connect the proper size and num-
ber of weld output cables (see Sec-
tion 2-8) to one of the welding power
source electrode terminals.
Connect the proper size and num-
ber of ground cables to one of the
welding power source work termi-
nals.
