QUICK-CONNECT “PIG-TAILS”

The Multi-Weld 350 is factory provided with two 21 in.(53 cm) long 2/0 AWG (70 mm2) “pig-tail” cables. Their 0.5" (13 mm) hole lug ends are routed through the “INPUT +” (on back) and “ELECTRODE +” (on front) cable channels of the Converter. They are attached to the bottom-accessed covered cable con- nection studs.

Attach the preferred standard, user-provided Quick- connect terminal (such as Lincoln Twist-Mate or Tweco

2-MPC type) to the cut-off end of these cables. Use the female connector on the “ELECTRODE +” cable and the male connector on the “INPUT +” cable.

ATTACHMENT AND ARRANGEMENT OF “PIG-TAILS”

To best suit the desired inter-connection of the Converters, the “pig-tail” cables may be routed into the front or back cable channels. For single or double “pig- tail” cables, route through the bottom-accessed cov- ered cable connection studs. (See Figures A.1 and B.1.)

To connect the “pig-tail” cables to the Converter:

1.Stand the Converter vertically on its rear handle and skid to gain access to the bottom stud covers. Then remove the two 0.25"(6.3 mm) screws secur- ing each cover and fold out the cover insulation.

2.Route the appropriate “pig-tail” cable lug ends under the skid rail (for strain-relief) through the desired front and/or rear corner channels to the exposed 0.5" (13 mm) stud. Remove the flange nut with a .75" (19 mm) wrench.

NOTE: Input supply cable(s) must connect through “INPUT +” labeled channels, and output weld cable(s) must connect through “ELECTRODE +” labeled channels.

3.Slip the “pig-tail” cable lug(s) over the stud and re- secure the flange nut. Make sure that the lug(s) do not touch any sheetmetal of the stud housing. Fold back the cover insulation and replace the stud cover.
