Gas monitoring
Depending on where the gas sensor is situated, the use of a pilot static tube and the
welding process monitoring phase.
------- Function disabled (ex works).
------- Monitoring during the welding process. Gas sensor between gas valve and
welding torch (with pilot static tube).
------- Monitoring prior to the welding process. Gas sensor between gas valve and
welding torch (without pilot static tube).
------- Permanent monitoring Gas sensor between gas cylinder and gas valve (with
pilot static tube).
