SGW-250SS — WELDER OPERATING INSTRUCTIONS
CAUTION :
NEVER NEVER NEVER NEVER NEVER switch the CV/CC Selector Selector Selector Selector Selector
Switch Switch Switch Switch Switch during any welding operation.
When switching a selector switch, fully
rotate it to the right or left position.
1. Turn the CV/CC Selector Switch Selector Switch Selector Switch Selector Switch Selector Switch
(Figure 10) to the CV CV CV CV CV position, and adjust voltage using
the V V V V Voltage Control oltage Control oltage Control oltage Control oltage Control knob.
2. Turn the CV/CC Selector Switch Selector Switch Selector Switch Selector Switch Selector Switch (Figure 11) to the CC CC CC CC CC
position.
Figure 11. Welding Current Adjustment
NOTE
When the CV/CC Selector Switch Selector Switch Selector Switch Selector Switch Selector Switch is in the CV position,
the Current Control Current Control Current Control Current Control Current Control , and Current Range Selector Current Range Selector Current Range Selector Current Range Selector Current Range Selector
Switch Switch Switch Switch Switch functions are inoperative.
NOTE
When the CV/CC Selector Switch Selector Switch Selector Switch Selector Switch Selector Switch is in the CC position,
the V V V V Voltage Control oltage Control oltage Control oltage Control oltage Control function is inoperative.
NOTE
When using the Current Control Current Control Current Control Current Control Current Control knob to adjust the current
output, the outer scale is for the high range, and the inner
scale is for the low range.
3. Set the CC CC CC CC CC Current Range Selector Switch Current Range Selector Switch Current Range Selector Switch Current Range Selector Switch Current Range Selector Switch to the
desired position (Low/High).
4. Adjust current output, by setting Current Control Current Control Current Control Current Control Current Control knob
to desired current output.
Auxiliary AC Power
The Auxiliary AC power in most cases will not be affected
by the CV/CC Selector Switch or any controls (Figure 12)
on the front panel, and will supply a stable constant AC
voltage except when the welding mode is activated.
Figure 10. Welding Voltage Adjustment
NOTE
When welding, remember that the output of the AC
AUXILIARY POWER is affected by the welding
operation. See next page for generator output voltage
conditions when welding.
