Initial Machine Startup

Inspection

Check the hydraulic fluid level to ensure it is at the correct
level as shown in Figure 7-1. Refer to Section 3 for speci-
fications on the hydraulic fluid, the fluid cap, strainer and
the correct fluid level. Check for any leaks on the floor or
under the cabinet. Make sure both the hydraulic system
service doors and the electrical cabinet service doors are
closed. The hydraulic system service doors are interlocked
to prevent machine operation with the doors open. Figure
2-9 shows a typical door interlock device and the mating
receptacle in the cabinet.

Apply Power

AC Power
After supplying electrical power to your welder, turn on
the AC power switch as shown in Figure 3-7. See Power
Requirements, Page 146.
Machine Air
The welder requires a supply of clean, dry, compressed air
at 75 to 90 psi. The connection is made using 1 /2 inch O.D.
tubing at the pneumatic lockout device. Turn the valve to
the right as shown in Figure 7-2 to open the valve and apply
the compressed air. The air is used to raise and lower the
front access door and for any optional vacuum part–reten-
tion or pneumatic clamping and ejection features.

press the E-STOP RESET button. The flashing alarm
light will go out. If the light does not go out, check the
rear service doors. They should be securely closed, and
the door interlocks should be engaged.
