Likely problems or items to check - in order from most likely to least
likely:
1. Arc actually popped out. Check gun lift, Check for surface
contaminants / try again. If it is consistent, it is an internal
failure.
2. Damaged/Broken connection from the current sensor (See
picture below) to J24 of FACS input board.
3. Pilot arc circuit - Look for evidence of a pilot arc. If no pilot arc
mark on the work material, replace the pilot arc board.
4. Check that the main relay pulled in during the start-up process.
When the main relay is closed, there should be 0V between
the two power terminals of the power input relay board. If the
voltage is higher, the input board main relay is not energized.
Replace the
power
input relay board.
8.3.5 E005 Regulation Error - Short circuit
Fatal, meaning you have to power down to continue welding
>> No
Acknowledge, meaning the error will exist as long as the unit
is powered on. (Note, welding can continue while the error
exists)
>> Yes
Description:
If the FACS output SMPS board senses that the current was 150% or
higher of the current setting while the control to the power system was
at the minimum output for >15ms, it will abort the weld and display this
error. This will happen if the current sensing fails for any reason (wiring,
power supply, etc.).
