OPERATION

B-2

Refer to Figure B.1b.

4. Circuit Breaker – Protects machine from damage if

maximum output is exceeded. Button will extend
out when tripped (Manual reset).

5. Gun Trigger - Activates welding output, wire feed,

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.

FIGURE B.1b

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.

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.
