Description
[EN] [150A]
EN Amperage: Use with AC TIG only to select electrode negative amperage value.
[EP] [150A]
EP Amperage: Use with AC TIG only to select electrode positive amperage value.
Average Amperage Control
Setting EN Amperage, EP Amperage, Balance, and Frequency values creates an average amperage.
The operator can change the average amperage value while maintaining the same EN amperage to EP
amperage ratio at the existing balance and frequency. To change the average amperage value, press the
Amperage button and rotate the Encoder control. The changing average value is displayed on the am-
meter. Example: If EN Amperage is 150, EP Amperage is 100, Balance is 75%, and Frequency is 120, the
average amperage is 138 amps. If you press the Amperage button and rotate the Encoder control until 69
amps is displayed, the EN amperage is now 75 and EP amperage is now 50. The balance remains 75%,
and the frequency is still 120, and the 1.5 to 1 EN amperage to EP amperage ratio is maintained.
