AUXILIARY POWER
Three AC auxiliary power supplies are included in the
Invertec V300-I: 24 VAC, 42 VAC and 115 VAC.
The 24 VAC supply is rated at 1 amp and provides
power for the LN-25 wire feeder. Protection is provid-
ed by a self-resetting current limited.
The 42 VAC supply is rated at 5.5 amps and provides
power for other wire feeders. Protection is provided by
a 6-amp circuit breaker with a reset button located on
the rear control handle.
The 115 VAC supply is rated at 2 amps and provides
power for the LN-7 wire feeder. Protection is provided
by a 2.5-amp circuit breaker with a reset button locat-
ed on the rear control panel.
The 24, 42 and 115 VAC supplies must not be loaded
at the same time.
NOTE: 110/115 VAC is not available on Codes 9827,
10037 and 10133.
OVERLOAD PROTECTION
The machine is electrically protected from producing
high output currents. Should the output current
exceed 340-360A, an electronic protection circuit will
reduce the current (“Fold Back”) to approximately
150A. The machine will continue to produce this low
current until the protection circuit is reset. Reset
occurs when the output load is removed.
THERMAL PROTECTION
Thermostats protect the machine from excessive
operating temperatures. Excessive temperatures may
be caused by a lack of cooling air or operating the
machine beyond the duty cycle and output rating. If
excessive operating temperature should occur, the
thermostat will prevent output voltage or current. The
meter will remain energized during this time.
