5.7.2.2 Setting the shielding gas quantity
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!
