Push-button, gas test/purge hose package
• ----------- Gas test:
Shielding gas (symbol flashes slowly) will flow for approximately 20 seconds
after pressing the push-button once. Press the button again to cancel the pro-
cess early.
• ----------- Purge hose package:
Press push-button for about 5 sec: Shielding gas flows permanently (mac 300
s) until the Gas test push-button is pressed again (shielding gas flashes fast).
All functions run without current (set-up phase). This provides a high degree of safety for the welder,
since the arc cannot be inadvertently ignited. The following parameters can be monitored during the wire
configuration:

5.7.1 WPQR welding data assistant
The cooling-down time from 800°C to 500°C essential for the welding result (known also as t8/5 time) can
be calculated using the input data in the WPQR welding data assistant. Prerequisite is the prior determi-
nation of the heat input. Upon input of the values, the valid t8/5 time is displayed with a black background.
