3-2 SELECTING AND PREPARING WELD OUTPUT CABLES.
1.- Weld Output Cable. Determine total cable
length in weld circuit and maximum welding
amperes. Use Table 3-1 to 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 connecting to work
clamp, or electrode holder.
3.- Insulated Electrode holder.
4.- GTAW torch. Install according to
manufacturer's instructions.
5.- Work Clamp. Install onto work cable.

* Weld cable size (AWG) is based on either a 4 volts or less drop or a current density of not more than 300 circular mils
per ampere. Use weld cable with insulation rating equal to or greater than the open-circuit voltage of the unit.
