CHAPTER 2: INSTALLATION AND SETUP
125ADP/300ADP/1000ADP DUAL PULSE RESISTANCE WELDING POWER SUPPLY
990-922 2-9
4. Connect a Model FS2L or FS1L Foot Switch to the Power Supply
FOOT SWITCH
connector.
5. Refer to the weld head manufacturer's User Manual for instructions on connecting the weld
head air valve solenoid cable to the Power Supply
AIR VALVE DRIVER
connector.
6. Connect a properly filtered air line to the air inlet fitting on the weld head. Use 0.25 inch O.D.
by 0.17 inch I.D. plastic hose with a rated burst pressure of 250 psi. Limit air line length to less
than 40 in. (1 m) or electrode motion may be slow.
NOTES:
●
EZ-AIR
operates from 85 to 130 psi.
● Use lubricators
only
with automated installations.
7. Turn air system ON and check for leaks.
8. Set the
WELD/NO WELD
switch on the Power Supply front panel to the
NO WELD
position. In
this position, the Power Supply cannot deliver weld energy, but it can activate the weld head.
9. Set the ON/OFF switch on the rear panel of the Power Supply to the ON position.
10. Press the foot switch part way to actuate the
first level
switch. The weld head upper electrode
should descend smoothly to the DOWN position. When it reaches the down position, release
the foot switch and proceed to Step 12. If the upper electrode does
not
operate smoothly,
proceed to Step 11.
11. Adjust the weld head down speed knob and repeat Step 10 until the upper electrode descends
smoothly.
12. Press the foot switch all the way down to close both level switches. The weld head upper
electrode should descend smoothly to the DOWN position, and then send the firing switch
signal back to the Power Supply when the preset electrode force is reached. After firing, the
upper electrode should ascend smoothly back to the UP position.
