OPERATION MANUAL
1.0 INTRODUCTION
This manual covers basic set up and maintenance of the following model 9 and
model 9E series weld heads: 9-750, 9-1500, 9E-1500, 9-2500, 9E-2500, 9-3500,
9E-3500, 9-4500, 9E-4500, 9ER-4500, 9-7500 and 9E-7500. The operator
should have a working understanding of the power supply being used and should
understand this manual before operating the weld head.
2.0 UNPACKING
When unpacking the weld head use extreme caution in removing the plastic bag
covering the cable connectors. Tools such a knife of other sharp object can cut
the cables.
3.0 CABLE HOOK UP
CAUTION
Always turn the power supply off before making any cable connections.
The Model 9 series weld heads come supplied with an integral 10ft (3 m) cable.
This cable is NOT connected directly to the power supply. It must be mated to
the power supply via an adapter pig-tail or adapter cable. Extension cables may
also be used. The use of an extension cable does not eliminate the requirement
for an adapter. If an extension cable is used, it is connected between the power
supply and the adapter. After making connections, slide the rubber boots
together. See figures 1 - 4
Fig. 1
Connect the power and ground fittings by pulling the brass ring back and
inserting the male fitting into the female fitting, until it is fully seated. If it is not
fully seated, it will leak water or potentially come apart.
