SECTION III - INSTALLATION
3.3 ADAPTER CABLE INSTALLATION (continued)
4. Insert the Service cable male gas quick-disconnect into the M-227 ARC
GAS OUTPUT connector.
5. Insert the two coolant quick-disconnects into the COOLANT IN and
COOLANT OUT connectors on the CW (if being used). The cable
coolant connectors are interchangeable and it does not matter which one
goes to in or out.
3.4 WELD HEAD INSTALLATION - The weld head cable connects to the adapter
cable. Refer to the Weld Head Operation manual as you perform this installation.
1. The male brass quick dis-connect on the adapter cable provides the electrode
power and one leg of the coolant path. Connect it to the mating female
quick dis-connect on the Weld Head.
2. Connect the other coolant quick dis-connect and gas quick dis-connect (they
are different types and sizes) to their mates on the Weld Head Cable.
3. After the Electrode, Coolant and Gas connectors are secure and checked,
slide the rubber boots on each line together and secure them in place. These
boots provide both a safety factor to prevent shorting to ground and also act
as a retainer to prevent the connectors from coming apart.
4. Unscrew the CONTROL connector dust caps on both cables just before
installing. Insert the adapter connector into the head connector. Note the
positioning keyway and NEVER FORCE or use tools on the cable
connections. Using just your hand, tighten the connecting ring until the pins
are firmly seated. Screw the two dust caps together to prevent them from
swinging around.
3.5
GROUND (WELDING WORK) CABLE INSTALLATION
1. A 50 ft Ground Cable with a “C” type clamp on one end and a Cam-lok quick
dis-connect is provided.
2. Connect the quick dis-connect to the GROUND connector on the M-227 or
the Ground Extension Cable if one is provided.
3. Connect the Ground Clamp to a “bare” metal surface on the Pipe to be
welded. It should be placed as close to the weld as possible.
