TIG welding
• Fasten the gas hose to the shielding gas connecting nipple at the back of the machine using the crown
nut.
5.8.1
TIG cold or hot wire welding
• Screw the gas hose connection nipple (intermediate hose package) onto the output side of the
pressure regulator.
5.8.2
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!
