SGW-250SS —WELDER OPERATING INSTRUCTIONS
CAUTION :
NEVER switch the CV/CC Selector Switch during any welding operation. When switching a selector switch, fully rotate it to the right or left position.
NOTE
When the CV/CC Selector Switch is in the CC position, the Voltage Control function is inoperative.
1.Turn the CV/CC Selector Switch (Figure 10) to the CV position, and adjust voltage using the Voltage Control knob.
3.Set the CC Current Range Selector Switch to the desired position (Low/High).
4.Adjust current output, by setting Current Control knob to desired current output.
NOTE
When using theCurrent Control knob to adjust the current output, the outer scale is for the high range, and the inner scale is for the low range.
Figure 10. Welding Voltage Adjustment
NOTE
When the CV/CC Selector Switch is in the CV position, the Current Control , and Current Range Selector Switch functions are inoperative.
2.Turn the CV/CC Selector Switch (Figure 11) to the CC position.
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.

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.
