For Converters (operating at rated output) less than 200 ft. (61 m) from the power source, the following min- imum cable sizes are recommended for the indicated quantity of Converters supplied by the input cable run to keep cable temperature and voltage drop within acceptable limits:
Converters | Cable Size |
| |
on Cable | AWG (mm2 ) |
| |
1 | 1/0 | (50) |
|
2 | 2/0 | (70) |
|
3 | 3/0 | (95) |
|
4 | 4/0 (120) |
| |
5 | 2x3/0 | (2x95) |
|

The output “Electrode” cable should be 2/0 AWG (70 mm2) if sized for rated output up to 200 ft.(61 m) from the Converter. If paralleled, the output cable to the arc should be 4/0 (120 mm2).
POWER SOURCE SETUP
Refer to the Instruction Manual provided with the Multi- Source power source, or other DC power source being used, for input power supply connections, output con- nections and controls setup.
In general:
1.Connect the positive (+) output connection terminal to the input supplying the
2.If not using a
a.If an inductance control, or tap, is selectable, use lowest inductance.
b.Use CC (Constant Current) mode for maximum supply voltage.
c.Set panel output control to maximum for maxi- mum current capacity.
d.Activate output with the “output terminals on” switch, or jumper

WARNING
Do not disconnect the Work clip lead without first switching OFF the Converter panel switch. Failure to do so will allow the Work lead clip to be electrically “hot” to work and “hot” to the electrode, through the circuit of the Converter, for about 5 seconds until the input con- tactor opens.
