7. Place another screwdriver or similar object into the
opening between the endcap and the base to keep the
first corner of the endcap from returning to its original
position when you release the other corner.
8. Repeat steps 5 and 6 on the other corner of the endcap.
9. If you are completely removing the endcap to replace it,
rather than removing it for better access to the interior of
the power supply, you must also disconnect the torch
lead, work lead, and ground clip from the front endcap or
the power cord and gas supply connector from the rear
endcap.
10. To replace the endcap, push it into the base to re-engage the snaps and then tighten the retaining screw. On
the rear endcap, make sure that the hole in the ground clip is aligned with the screw holes in the endcap and
the power supply before attempting to insert the retaining screw.

1. Turn OFF the power, disconnect the power cord, and disconnect the gas supply.
2. Use a #2 Phillips screwdriver to remove the 2 screws from the handle on the top of the power supply. Tilt the
endcaps back slightly so that you can get the edges of the handle out from underneath the endcaps. Remove
the handle and then lift the cover off the power supply. Remove the Nomex barrier that protects the power
board.
3. Compress the collar on the hose fitting and pull the hose from the fitting to remove the gas hose from the
