1 Weld Output Cable

Determine total cable length in weld circuit and maximum welding am- peres. See Section 4-8to select proper cable size.

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.
