Gas Test - Setting The Shielding Gas Volume; Rinse Hose Package Function - EWM Taurus 551 Basic FDG Operating Instructions Manual

Gas test – setting the shielding gas volume
5.1.9.3
•
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.
•
You can activate the gas test on the machine control (see Control operating instructions) or by
pressing the "Gas test/rinse hose package
motor remain switched off – no unintentional ignition of the arc). Some welding systems have several
push-buttons to set the shielding gas. The push-button is generally found near a wire feeder.
Shielding gas flows for around 25 seconds or until the button is pressed again.
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!
