Gas Test - Setting The Shielding Gas Volume; Rinse Hose Package Function - EWM Taurus 355 Basic TKW Operating Instructions Manual

Gas test – setting the shielding gas volume
5.1.8.3
If the shielding gas setting is too low or too high, this can introduce air to the weld pool and may cause
pores to form. Adjust the shielding gas quantity to suit the welding task!
•
Slowly open the gas cylinder valve.
•
Open the pressure regulator.
•
Switch on the power source at the main switch.
•
Set the relevant gas quantity for the application on the pressure regulator.
•
The gas test can be triggered by briefly pressing the Gas test/Rinse hose package push-button
either at the control or underneath the protective cap next to wire feeder (welding voltage and wire
feed motor remain switched off, no unintentional arc ignition).
Shielding gas flows for around 25 seconds or until the button is pressed again.
