For Example,
Total Cable
Length In Weld
Circuit = 20 ft (6 m)
1 Weld Output Cable
Determine total cable length in weld circuit and maximum welding am- peres. See Section
Use shortest cables possible.
Do not use damaged cables.
2 Terminal Lug
Use lugs of proper amperage capacity and hole size for connect- ing to work clamp, electrode holder, and weld output terminals.
3 Insulated Electrode Holder
Install according to manufacturer’s instructions.
4Work Clamp Install onto work cable.
