Condition 1:
After several seconds, the fan switches on, and the heat-sink warms
up to 43 °C
-
Condition 2:
Approx. three and a half minutes after being switched on, the power
source switches off once the heat-sink has heated up to 93 °C
-
Condition 3:
The fan must continue to run
-
Condition 4:
The “Fault” indicator lights up
-
Condition 5:
After approx. six and a half minutes, the power source automatically
switches back on once the heat-sink has cooled down to 60 °C
-
Condition 6:
The “Fault” indicator goes out
- Set the welding-current dial to Minimum
- After a few more minutes, the fan cuts out once the heat-sink has cooled to a
temperature of 41 °C
