DESCRIPTION Of OPERATION
The side mounted fan M1 is used to circulate cooling air across the active devices, (the IGBTs, IBR and
D101 and D102) inside the cabinet. The fan starts when the torch trigger is depressed and will continue to
run for up to seven minutes after the cut has ceased. There is a variable timing circuit at work here. The
timing circuit will keep the fan running for the same amount of time the torch was cutting. In other words,
if the torch was turned on for two minutes, the fan will continue to run for two minutes after the torch was
turned off. This 1:1 ratio will work up to a maximum of seven minutes. The maximum fan on time is seven
minutes after the torch is turned off.
The fan input power wire is connected on one
side to the 230-volt primary at the T2 trans-
former, and the other wire is connected to
the power board PCB2 at J2. The J2 connec-
tion is routed to the Fan relay, RL2, for ac-
ti-
vation from the main control board PCB1. The 230
volt AC power connection is completed through the
contacts of RL2, to J42
Testing:
Open circuit resistance is 150 Ohms.
