Torch Trigger / gas Test Switch
The torch trigger positions are converted to mechanized logic on the mechanized consoles.
Operating modes:
Normal pilot Arc (CENTER position) - The pilot arc will not re-strike automatically. Requires a new start signal.
This setting is recommended for standard plate cutting.
Continuous pilot Arc (DOWN position) - The pilot arc will re-strike automatically. Examples for usage of this
setting are expanded metal and grate cutting.
Test Mode:
gas Test Switch (UP position) - The display screen will indicate flowing air pressure. The air regulator should be
adjusted to recommended pressure before cutting operations. Allow air to flow for a few minutes. This should
remove any condensation that may have accumulated during shutdown period. Be sure to place switch in
Normal pilot Arc (CENTER position) or Continuous pilot Arc (DOWN position) before starting cutting opera-
tions.
E. Display Screen: Initially displays the Current Setting during normal operation, then displays the actual Arc Voltage
once an arc is established. The display will return to the Current Setting when the arc is no longer present.
1. power-up Indication: When unit is initially switched on the Model, PIP (Parts in Place), Software version will be briefly
displayed. Display will then initially show the Current Setting.
2. gas Test: When unit is in the "GAS TEST" mode the display will indicate air pressure setting in psi/bar.
3. fault Indication: Should a fault condition exist in normal operation, the display will show a code number. Refer to the
"Help Code" menu on the front panel (non-"CE" units only) or in Section 4.1.F and in Troubleshooting Section 6.1.
