Gas test or "rinse hose package"

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.
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. Conduct a gas test > see 5.9.8.1 chapter
•
Set the required amount of shielding gas on the pressure reducer, about 4 - 15 l/min depending on the
current strength and the material.
