OPERATION

FAN

The cooling fan on the ES 276i operates once 15
amps of welding current is drawn and for 7 minutes
after the output current has stopped flowing.
The fan will also run anytime the machine has over
heated.

POWER-UP SEQUENCE

At power up the thermal light turns on and the fans
run for approximately 3 seconds. This is the pre-
charge time for the main capacitors. After this time
the fans and thermal light turn off and the pre-charge
relay closes to apply full line power to the capacitors.
At this time the machine is ready to weld.
