A-4 INSTALLATION
PRO 100
A-4
Connecting Gun Cable to the PRO 100
1. Refer to Figure A.2. Unplug the machine or turn
power switch to the OFF “ O ” position.
2. Pass the insulated terminals of the gun trigger con-
trol leads, one at a time, through the Gun Cable
and Control Lead Access Slot (2) in the case front.
The leads are to be routed under the Wire Feed
Gearbox (6) and through the Cable Hanger (7) on
the inner panel.
3. Insert the connector on the gun conductor cable
through the Gun Cable Access Hole (2) in the
PRO 100 case front. Make sure the connector is all
the way in the brass connector block. Unscrew
thumbscrew on the connector block a few turns if
gun connector will not insert fully. Rotate the con-
nector so control leads are on the underside and
tighten the Thumbscrew (8) in the connector block.
4. Connect the gun trigger control lead terminals to
the two insulated 1/4" (6,4 mm) tab terminal con-
nector bushings located above the
“ Gun Trigger
Connection ” decal in the wire feed section (4).
Either lead can go to either connector. Form the
leads so that they are as close as possible to the
inside panel.
If the gun trigger switch being used is other than
that supplied with the PRO 100, the switch must
be a normally open, momentary switch. The termi-
nals of the switch must be insulated from the
welding circuit. Malfunction of the PRO 100 may
result if this switch shorts to the PRO 100 welding
output circuit or is common to any electrical cir-
cuit other than the PRO 100 trigger circuit.
GAS CONNECTION (OPTIONAL)
When using the GMAW process, a K610-1 MIG con-
version kit and a cylinder of carbon dioxide (CO2) or
argon-carbon dioxide mixed shielding gas must be
obtained. For more information about the K610-1 MIG
Conversion Kit for use with the PRO 100, refer to the
ACCESSORIES section.
Work Cable Installation
Refer to Figure A.2.
1. Open the wire feed section door on the right side of
the PRO 100.
2. Pass the end of the work cable that has the termi-
nal lug with the smaller hole through the Work
Cable Access Hole (1) in the case front.
3. Route the cable under and around the back of the
Wire Feed Gearbox (6).
4. For Innershield Only: Refer to Figure A.2. As
delivered, the PRO 100 is connected for negative
electrode polarity. This is the appropriate configu-
ration for the Innershield process. To complete
installation, use the provided wing nut to connect
the work cable
’ s terminal lug to the positive (+) out-
put terminal (5) located above the Wire Feed Gear-
box (6). Make sure that both wing nuts are tight.
5. For GMAW Only: Refer to Figure A.4. To wire for
positive polarity (required for the MIG process),
connect the short cable attached to the connector
block (1) to the positive (+) output terminal (4) and
the work cable (3) to the negative (
– ) terminal (2).
FIGURE A.4
GUN INSTALLATION
As shipped from the factory, the PRO 100 gun is
ready to feed 0.035
” (0,9 mm) wire. If .023" – .025"
(0,6 mm) or .030" (0.8 mm) wire is to be used for the
GMAW (MIG) process, see the MAINTENANCE sec-
tion for proper configuration of feeding components
and installation details.
