1 - 1. GENERAL INFORMATION AND SAFETY A. General Information presented in this manual and on various labels, tags, and plates on the unit pertains to equip- ment design, installation, operation, maintenance, and troubleshooting which should be read, understood, and followed for the safe and effective use of this equip- ment.
2 - 2. GAS/CURRENT SENSING CONTROL CON - NECTIONS (Figures 2-1 And 2-2) N-. ELECTRIC SHOCK can kill. • Do not touch live electrical parts. • Shut down unit, welding power source, and robot, and disconnect input power employing “lockout/tagging procedures” before making in - terconnections.
A. Wire Stick Sensing Connections 1. Align keyway, insert four-socket Amphenol plug into matching receptacle on computer interface, and rotate threaded collar fully clockwise. 2. Connect lead with ring terminal to welding power source positive output terminal.
3. Remove welding power source interface side panel. 4. Route remaining cord from computer interface through strain relief in bottom of welding power source interface, to 14-position terminal strip. 5. Connect leads as follows: a. Red lead to terminal 52.
3 - 1. POWER SWITCH (Figure 3-1) 3 - 4. VOLTMETER (Figure 3-1) Placing the POWER switch in the ON position applies input power to the interface. The interface must be on for the robot to weld. Placing the POWER switch in the OFF position shuts down the interface.
4 - 2. OUTPUT SIGNALS FROM COMPUTER IN - TERFACE (Figure 4-2) - The interface interprets the input signals from the welding power source, wire drive motor, robot, and wire stick check circuit. The output of the computer interface regulates the welding power source and wire feed functions while welding.
CAUTION: IMPROPER FUSES can damage this If replacement becomes necessary, use only fuses of the proper size, type, and rating (see Parts List). To replace the fuse, proceed as follows: 1. Depress and rotate fuse holder cover counterclockwise. 2. Pull out fuse with cover when fuse holder cover is free.
2. Remove screws securing board to stand-offs. Do not remove stand-offs. 3. Disconnect plugs PLG2O and PLG24 from mat - ching receptacles on PC4. 4. Gently pull board straight away from front panel. Do not pull up or down; otherwise, the meters and LED’s may be damaged.
c. Slide spacers onto new meter support. d. Push meter into socket with meter supports protruding through to rear of PC4. e. Reinstall lock washers and nuts to secure meter to board. Do not overtighten nuts or meter may be damaged. 6. To install replacement display board, carefully line board up with front panel openings for meters and LED’s.
TROUBLE PROBABLE CAUSE REMEDY No wire feed. Robot signal. Check input signal from robot to motor board PC2. Signal should be 0-10 vdc between pins K and B (common) on RC5. - Relay CR1 not working. Replace CR1. Motor board PC2 not work- ing. Replace PC2 (see Section 5-4).
5 - 6. USE OF INDICATOR LIGHTS FOR TROUBLESHOOTING Ga~ Indicator Light I Gas does not flow: IF Gas flows: IF Gas dodes not flow: System normal (on). Check gas valve operation. Check gas valve operation and gas line for leaks. Check interface board PC3.
