6.8.1.3 Shielding Gas Supply
CAUTION
Incorrect handling of shielding gas cylinders!
Incorrect handling of shielding gas cylinders can result in serious and even fatal injury.
• Observe the instructions from the gas manufacturer and in any relevant regulations
concerning the use of compressed air!
• Place shielding gas cylinders in the holders provided for them and secure with fixing
devices.
• Avoid heating the shielding gas cylinder!
NOTE
Before connecting the pressure reducer to the gas cylinder, open the cylinder valve
briefly to expel any dirt.
• Tighten the pressure reducer screw connection on the gas bottle valve to be gas-tight.
• Tighten gas hose on pressure reducer to be gas tight.
•
Slowly open the gas cylinder valve.
•
Open the rotating valve on the welding torch
Before each welding process, the rotating valve must be opened; after the welding process, it
must be closed.
•
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
