1. Lower start gas flow.
2.a). Pump pressure too low,
should be 90 - 100 psig.
b). Faulty coolant flow switch.
c). Obstruction in torch limiting
coolant flow.
3. Service torch as outlined in the
torch manual.
4. Trouble shoot signal path.
5. Check for proper pressure and
flow.
6. Run through all setup procedures.
1. Lower arc voltage in small (5 Volt)
increments.
2. If cutting speed is too fast,
decrease speed.
3. a). Wrong nozzle being used.
b). Lower current into correct
operating range.
1. Raise the arc voltage in small
increments (5 Volts).
2. Simply increase speed.
3. Change to a higher current
nozzle.
