| GTAW (TIG) WELDING |
|

|
|
|
|
| The POWER FEED™ / Power Wave system is excel- | ||||
|
|
| lent for Touch Start TIG welding. |
|
|
|
|
|
|
| The system supports TIG torches with or without gas | ||||
|
|
| control valves. TIG torches with gas control valves | ||||
|
|
| connect directly to the gas flow regulator. For TIG | ||||
|
|
| torches without gas control valves, connect the output | ||||
|
|
| gas hose on the wire feeder to the TIG torch gas | ||||
|
|
| hose. |
|
|
|
|
|
|
| The wire feeder gas solenoid may be enabled or dis- | ||||
|
|
| abled by parameter P.8 in the | ||||
|
|
