NOTICE − Do not switch under load. Stop en- gine or set Process/Contactor switch to any Remote position before switching.

Use switch to select weld or battery charge output. Output automatically decreases (but does not stop) when terminal voltage is 15 to 25 percent above required battery voltage.

.Before connecting charging cables, place

Output Selector switch in position match- ing voltage of battery being charged.

When done charging, stop engine or set Pro- cess/Contactor switch to any Remote On/Off Switch Required position. Move Output Selec- tor switch to AC Weld or DC Weld position.

BATTERY COLD CRANK AMP RATING (CCA)

1Battery Charging Current Chart

Find battery cold crank amp (CCA) rating on battery. Use CCA rating on chart to find charge current set- ting for battery.

EXAMPLE: If battery CCA rating is 500, charging current from chart is 100 amperes.

Do not exceed charging current found on chart. For longer battery life, use lowest charge rate possible.
