Work Cable Installation
Refer to Figure A.2.
1. Open the wire feed section door on the right side of
the SP-100T.
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 GMAW Only: Refer to Figure A.2. As deliv-
ered, the machine is connected for positive elec-
trode polarity. This is the appropriate configuration
for the GMAW (MIG) process. To complete installa-
tion, use the provided wing nut to connect the work
cable
’ s terminal lug to the negative ( – ) output ter-
minal (5) located above the Wire Feed Gearbox
(6). Make sure that both wing nuts are tight.
5. For Innershield Only: Refer to Figure A.4. To wire
for negative polarity (required for the Innershield
process), connect the short cable attached to the
connector block (1) to the negative (
– ) output termi-
nal (2) and the work cable (3) to the positive (+)
terminal (4).

Connecting Gun Cable to the SP-100T
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 SP-
100T case front. Make sure the connector is all the
way in the brass connector block. Unscrew thumb-
screw on the connector block a few turns if gun
connector will not insert fully. Rotate the connector
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 below 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 SP-100T, the switch must be
a normally open, momentary switch. The terminals
of the switch must be insulated from the welding
circuit. Malfunction of the SP-100T may result if
this switch shorts to the SP-100T welding output
circuit or is common to any electrical circuit other
than the SP-100T trigger circuit.
GAS CONNECTION
When using the GMAW process, a cylinder of shield-
ing gas, must be obtained. For more information about
selecting gas cylinders for use with the SP-100T refer
to the ACCESSORIES section.

GUN INSTALLATION
As shipped from the factory, the SP-100T is ready to
feed .023"
– .025" (0.6 mm) solid wire. If .030" (0.8
mm) solid wire is to be used, change the contact tip to
the appropriate size.
NOTE: If .035" (0.9 mm) Innershield flux-cored wire is
to be used, the .035
” Innershield Welding kit is
required (see ACCESSORIES section).
