3. Insert the two coolant line quick-disconnect fittings on the pig-tail into the mating
WATER OUT and WATER RETURN connectors on the Model 205-CW.
These connectors are interchangeable so either connector may be connected to
either mating fitting. To prevent accidental disconnection after making the
connection, finger-tighten the lock screw on the male connectors.
4. Attach the weldhead control male connector on the weldhead to the WELDHEAD
CONTROL connector on the Model 205. Note the positioning keyway and
NEVER FORCE or use tools on the cable connectors. Hand-tighten the connecting
ring being careful not to cross-thread the ring.
5. Insert the male gas quick-disconnect fitting on the weldhead to the mating ARC GAS
OUTPUT connector on the Model 205 and hand-tighten the lock screw to
prevent accidental disconnection. Slide the rubber boot over the connection.
Adapter Cable Connections
1. Connect the ground and electrode brass quick-disconnect fittings on the adapter
cable to the mating fittings on the weldhead. Pull the knurled ring on the female
fitting back and fully insert the male fitting. These connectors are fully seated when
the ring will spring back to its original position. Slide the rubber boots together and
secure them in place, being careful not to dislodge the connectors. Male boots
should cover the connection first. The boots protect the connectors and prevent
shorting to ground.
2. Attach the weldhead control male connector on the weldhead to the mating
weldhead control female connector on the adapter cable. Align the keyways and
carefully screw the retaining ring in place. DO NOT use tools and be careful not to
cross-thread the fitting. To help prevent damage screw the connector dust caps to
each other.
3. Insert the male gas quick-disconnect fitting on the weldhead to the mating female
fitting on the adapter cable. Hand-tighten the lock screw to prevent accidental
disconnection. Slide the rubber boots over the connection and secure them
together.
4. Attach the ground and electrode connectors on the adapter cable to their respective
GROUND(+) and ELECTRODE(-) terminals on the Model 205. Align the
keyways, push in and turn clockwise until fully locked.
