Shielding Gas Supply - EWM PICO 162 Operating Instructions Manual

6.8.1.3

Shielding Gas Supply

No dirt must be allowed to enter the shielding gas supply, as this would cause blockages in the
shielding gas supply. All shielding gas connections must be gastight.
• Place shielding gas cylinder in the retainer provided for it and secure with chains.
Before connecting the pressure reducer to the gas cylinder, open the cylinder valve briefly to blow out
•
any dirt.
Mount the pressure reducer onto the gas cylinder valve.
•
Screw the gas hose of the welding torch tightly to the pressure regulator.
•
Slowly open the gas cylinder valve.
•
Open the rotating valve on the welding torch
•
• Set the required amount of shielding gas on the pressure reducer, about 4 - 15 l/min depending on the
current strength and the material.
Rule of thumb for gas flow rate:
Diameter of gas nozzle in mm corresponds to gas flow in l/min.
Example: 7 mm gas nozzle corresponds to 7 l/min gas flow
Before each welding process, the rotating valve must be opened; after the welding process, it
must be closed.
