TABLE B.1 – REQUIRED CABLE CONNECTOR KITS (For K684 MAGNUM® Guns)
INSTALLATION
ELECTRICAL SHOCK can kill.
• Have an electrician install and ser-
vice this equipment.
• Turn the input power off at the fuse
box before working on equipment.
• Do not touch electrically hot parts.
The 450WC gun can only be connected to a wire
feeder with a Lincoln Fast-Mate™ connector, a
European style gun connector or a wire feeder
equipped with an adapter. See Table B.1 for the vari-
ous adapters that are available. Install the adapter per
the Instructions sent with the adapter.
Check that the feeder outgoing guide, as well as the
drive rolls are appropriate for the electrode being
used. When using a Fast-Mate Adapter Kit, be certain
that the adapter guide tube is also correct.
Align and fully engage the brass connector end of the
gun into the mating connector on the outgoing side of
the feeder wire drive. Secure the cable connection by
tightening the Fast-Mate™ connector collar nut.
Connection to a Power Wave power source
equipped with a water cooler and K685 Synergic 7
wire feeder.
Connect the water hose quick connects to the recep-
tacles on the front of the wire feeder. When connect-
ing the hoses to the water supply, the WATER IN
“BLUE HOSE” must be connected to the water out
connector on the wire feeder.
The WATER OUT “RED HOSE” must be connected to
the receptacle marked water in. The water cooler pro-
vided with the Powerwave will provide adequate flow
to cool the gun and has a safety switch that will pro-
duce a “beeping” noise to warn the welder that there
is no water flow. Do not weld until the flow problem is
corrected and “beeping” stops.
Connection to other water coolers.
The water cooler should be rated for .58 gallons per
minute (2.2 liters per minute) at 60 psi (4.08 atm) or
greater. The connectors on the gun water hoses
have a male quick connect fitting that will mate to a
Rectus® Series 21 Coupler. (Note: A KP1529-1
adapter is available to connect the male quick con-
nect to a CGA 033 left hand male connection). When
connecting the hoses to the water cooler, the
WATER IN
“BLUE HOSE” must be connected to the
water out connector on the water cooler. The
WATER OUT
“RED HOSE” must be connected to
the water in connector on the water cooler.
Do not operate the gun without having water flowing
through the gun. IRREPARABLE DAMAGE to the
gun will occur if incorrectly connected or if operated
even for a short time without an adequate supply of
cooling water. A flow sensor is recommended to pro
-
tect the gun. A K1536-1 flow sensor is available.
WARNING
CAUTION
ADAPTER FOR QUICK CONNECTION TO EXTERNAL CGA WATER FITTING.
A KP1529-1 adapter was designed to connect the quick connecting fitting on the water cooled gun water hoses to
a Compressed Gas Association (CGA) 033 left hand male connection. Two adapters are included in each kit.
