Setting the shielding gas quantity
NOTE
Rule of thumb for the gas flow rate:
Diameter of gas nozzle in mm corresponds to gas flow in l/min.
Example: 7mm gas nozzle corresponds to 7l/min gas flow.
Incorrect shielding gas setting!
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!

Press the "Select welding parameter" button and hold for approx. 5 sec.
The gas pre-flow time LED (TIG) will come on,
shielding gas flows for approx. 20 sec.
• Set the required amount of shielding gas on the pressure regulator, about 4 - 15 l/min depending on
the current strength and the material.
