Other common cause is one of the parts, tip, electrode or start cartridge, is missing. Install new parts. If still
E005 do the following:
a. If the Inverter board has just been replaced, a common cause of E005 is the wire #6 from the brass fitting
at the back of the front panel ATC isn't connected to the Faston tab J611 (Electrode).
b. If new parts don't solve the problem, make sure the torch tip is not grounded, not touching work or other
ground, measure for -12 to -15V volts between the torch tip and work.
c. If no voltage at the tip, measure from work to the Inverter board stud labeled TIP. If the voltage is at TIP
then there is a poor connection from TIP to the ATC pilot receptacle or through the torch lead or handle
to the torch head. Possibly at the torch handle Quick Disconnect.
d. If no voltage at the TIP stud replace the Inverter board.
e. If -12 to -15V volts is at the torch tip, measure for same voltage from work to the ATC electrode connection
(the brass fitting at the back of the front panel ATC). If it is there and the #6 wire as described in step a. is
connected then replace the Inverter board. If the -12 to -15V volts is not on the ATC electrode connection
then there is a poor connection between there and the electrode in the torch head. Possibly at the torch
handle Quick Disconnect. Could be damaged or missing canted coil spring.
