Soyer BMH-22i Operating Instructions Manual page 30

5.3.2.4 Operation mode "GAS" (gas test)
This operation mode checks whether the shielding gas flows through the gas shroud of the welding
gun or welding head. As long as a triggering signal is there, shielding gas flows out of the gas shroud
on the welding gun or welding head. This enables you to rinse the gas lines with shielding gas before
starting to weld.
• Select the operation mode "GAS" with the function key "arrow up" or "arrow down" (1 or 2).
• Connect gas supply
• The gas valve may be activated by
- the trigger of the welding gun or welding head
- an active start signal at the CNC interface
5.3.2.5 Operation mode "Electrode welding"
In the operation mode "Electrode welding" the stud welder works like a welding rectifier.
CAUTION
In this operation mode, an open-circuit voltage of about 80V (DC voltage) is always
applied to the terminals!
• Use the function key "arrow up" or "arrow down" (1 or 2) to set operation mode "ELECTRODE
WELDING".
