1 Weld Output Cable
Determine total cable length in weld
circuit and maximum welding am-
peres. Use Section 3-3 to select
proper cable size.
Use shortest cables possible.
Do not use damaged cables.
2 Terminal Lug
Use lugs of proper amperage ca-
pacity and hole size for connecting
to work clamp, electrode holder, or
wire feeder.
3 Insulated Electrode Holder
Install according to manufacturer’s
instructions.
4 Work Clamp
Install onto work cable.
5 Dinse-Type Connector
Install onto weld cable.
