Soyer BMH-22i Operating Instructions Manual page 28

5.3.2.1 Operation mode "OP" (operating state)
The operation mode "OP" allows normal welding operation with the welding parameters set.
• Use the function key "arrow up" or "arrow down" (1 or 2) to set operation mode "OP".
5.3.2.2 Operation mode "PRE" (preweld current test)
The adjustment "PRE" (preweld current test) enables you to carry out welds by means of the set
parameters without application of main current and serves to control the gun or head adjustment and
to test performance. During this operation mode, an arc is generated with low current when the gun or
welding head is positioned on the closed circuit (workpiece connected with earth) and the gun switch
is pressed (or when a signal is given via the interface). This is helpful to check the symmetry of the arc
or whether preweld current is flowing.
CAUTION
Protective goggles are required to carry out this test. Please also refer to the safety
instructions.
• Use the function key "arrow up" or "arrow down" (1 or 2) to set operation mode "PRE".
5.3.2.3 Operation mode "LIFT" (lift test)
This operation mode enables you to adjust and check the lift of the gun or welding head. For further
information, please refer to the operating instructions of the welding gun or welding head.
• Use the function key "arrow up" or "arrow down" (1 or 2) to set operation mode "LIFT".
