Connect the coolant hoses (19089 and 19090 sup-
plied with the Wire Feeder Connector Assembly)
to the mating coolant hose connectors of the gun.
The other end of the hoses are fitted with standard
CGA fittings designed to connect to wire feeders
mounted with optional coolant kit components (B-
size to coolant adaptor; C-size to power block adap-
tor).
E. VOLTAGE PICK-UP LEAD
Starting December 1, 1986, each MIG-41 gun includes
a voltage pick-up lead for connecting to the Digipulse
450 Pulsed Mig Welding system for better arc voltage
sensing. This lead has a single pin connector and ex-
tends about 8-in. from the wire feeder connector end
of the gun cable. The pick-up lead connects only to
Digipulse 450 system modified for this connection. The
modified units can be identified by locating a small
single-pin connector in the red wire externally con-
nected from the wire feeder control and attached to
the accessory support assembly of the wire feeder. For
more details refer to Insert for F-14-350 packed with
the Digipulse 450 System.
The pick-up lead is NOT required if using the MIG-41
gun with any other wire feeder. It is recommended that
it be disconnected from the gun as follows (see illus-
trations):
1.
Loosen the 3-piece adaptor support lock nut at wire
feeder connector end by turning it to the left and
then slide towards from end. The loose adaptor
support half can then be lifted off.
2.
Cut nylon tie-wrap securing the folded over pick-
up lead to power cable and discard the tie-wrap.
3.
Disconnect the pick-up lead from the lead in the
cable and discard the pick-up lead. Tuck the fe-
male connector end of the lead back into the gun
cable.
4.
Reassembly the 3-piece adaptor support.
