K499 Argon-Mixed Gas Regulator and Hose Kit

Install the pressure-flow regulator and gauge to a
cylinder according to the instructions in Section 1.10.
Connect one end of the 10 foot (3.0 m) hose to the
SP-100 gas inlet fitting and the other end to the regu-
lator fitting.

The K499 argon-mixed gas pressure-flow regulator is
preset by the manufacturer to deliver a nominal flow of
30 cubic feet per hour (14 1/min) of argon or argon-
mixed gas. This setting cannot be changed.

.035" (0.9 mm) Innershield Welding Kit

Includes a contact tip, gasless nozzle, and a cable
liner to permit the SP-100 gun and cable to use .035
(0.9 mm) diameter flux-cored electrode. Also included
is a spool of .035 (0.9 mm) Innershield

NR-211-MP.

The K549-1 Kit is for use with the Magnum™ 100L
gun (with red trigger). The fitting on the end of the
liner is stenciled with the maximum rated wire size
(.045"/1.2 mm).

The K464 Kit is for use with the earlier “Lincoln
Electric

” gun (with black trigger). The end of the brass

fitting on the end of the liner for .035 (0.9 mm) wire is
color coded green. The .023-.030 (0.6-0.8 mm) factory
installed liner is color coded orange.

See Maintenance and Troubleshooting Section for
instructions on installing liner and contact tip in gun.

K467 Input Line Cord

Same as line cord supplied with the SP-100 but has a
NEMA type 5-20P plug for use on a 25 amp branch
circuit with a nominal voltage rating of 115 volts to 125
volts, 60 hertz. Install per the following:

1. Turn the SP-100 Power Switch to OFF (“O”).

2. If connected, remove the line cord plug from power

supply receptacle.

3. Remove the two screws that hold the line cord

receptacle in the SP-100 flanged inlet connector
and disconnect the line cord from the SP-100.

4. Connect the S18410 input line cord receptacle to

the SP-100 and replace the retaining screws.

OPERATING INSTRUCTIONS

DUTY CYCLE

The SP-100 is rated at the following duty cycles.

(1)

Based upon 10 minute time period. (i.e. for 20% duty cycle it is 2
minutes on and 8 minutes off.)

(2)

Using Optional K467 Input line cord on a 25 amp branch circuit.

SELECTING A WIRE SPOOL SIZE

Select a spool size so that the wire is used up within a
six month period. This eliminates needless waste of
wire due to oxidation and rusting. Dirty, oxidized, or
rusty wire results in poor wire feeding and poor weld-
ing performance. This wire should be discarded.

FEEDING WELDING WIRE

When inching the welding wire, the drive rolls, the
gun connector block and the gun contact tip are
always energized relative to work and ground and
remain energized several seconds after the gun
trigger is released.

------------------------------------------------------------------------

1. Remove gas nozzle and contact tip from end of gun

according to instructions in the maintenance sec-
tion of this manual.

2. Turn the SP-100 ON (“I”).
3. Straighten the gun cable assembly.
