●
No external shielding gas is required when used
with Lincoln Innershield .035" (0.9 mm) NR ® -211-
MP electrode.
●
Accommodates both 4" (100 mm) diameter and 8"
(200 mm) diameter spools of wire.
●
Accepts optional Spot/Stitch Timer Kit.

WELDING CAPABILITY

The Pro-MIG 135 is rated at 90 amps, 19 volts, at
20% duty cycle on a ten minute basis. It is capable of
higher output currents at lower duty cycles.

LIMITATIONS

Arc Gouging cannot be performed with the Pro-MIG
135. The Pro-MIG 135 is not recommended for pipe
thawing or TIG welding.

CONTROLS AND SETTINGS

Refer to Figure B.1a.
1. Control Power ON/OFF Switch
— When the power is on the
fan motor will run and air will be
exhausted out the louvers in the
front of the machine. The weld-
ing output and wire feeder
remain off until the gun trigger
is pressed.
2. Wire Speed Control —
Controls the wire feed speed
from 50 – 300 in /min. (1.3 –
7.6 m/min.). The control can
be preset on the dial to the
setting specified on the Pro-
MIG 135 Application Chart
located on the inside of the
wire feed section door.
3. Voltage Control — A 4-posi-
tion tap selector switch gives
full range adjustment of
power source output voltage.
Do not switch while welding
as damage to switch may
occur.
4. Circuit Breaker – Protects machine from damage if
maximum output is exceeded. Button will extend
out when tripped (Manual reset) Refer to Figure B.1b.

and gas solenoid operation. Releasing the trigger
deactivates welding and simultaneously activates
the "burnback" function so that the welding wire
does not stick in the weld puddle.
(see ACCESSORIES section) - If present, replaces
Blank Panel Assembly located on the center panel
inside the case door:
Mode Switch - Selects between Spot, Stitch, or
Seam (normal welding) mode. Spot mode welds
for an adjustable length of time (set by Time
Control; see below) and then stops, whenever the
gun trigger is depressed and held. Stitch mode
cycles between welding and not welding for an
adjustable length of time (also set by Time Control)
while the gun trigger is depressed. In Seam mode
the machine will weld continuously while the gun
trigger is depressed. Releasing the gun trigger in
any of the three modes will interrupt welding imme-
diately.
Time Control - In Spot mode, controls spot mode
ON time between approximately .25 and 4.0 sec-
onds. In Stitch mode, controls stitch mode ON time
and OFF time simultaneously between .25 and 4.0
seconds each. This control is deactivated while in
Seam mode.
