6 – Power Supply Component Replacement

Detach and reattach the front panel

Several repairs are easier to make if you first detach the front panel from the power supply. For instructions on replacing
an old front panel with a new one, see

Replace the front panel

Detach the front panel

1.

Set the power switch to OFF (

O

), and disconnect the power cord from the power source.

2.

Remove the power supply cover. See

Remove the power supply cover

3.

Loosen the strain relief nuts on the torch lead

and work lead

.

4.

Lay the power supply on its side.

5.

Remove the retaining screw

from the bottom of the front panel

.

Figure 26

6.

Insert a blade screwdriver into the opening for
one of the snaps

. While pushing up on the

tab inside the snap, pull the corner of the front
panel away from the power supply until it
detaches from the base.

7.

Repeat the previous step on the other corner
of the panel.

8.

Disconnect the control board’s ribbon
cable

from the power board

by folding

the latches

back.



, the center panel is hidden in

the image on the left.

9.

Gently pull the panel away from the power supply.
