OPERATION

B-2

 

 

 

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.

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.

WELDING CAPABILITY

The SP-135T is rated at 90 amps, 19 volts, at 20% duty cycle on a ten minute basis. It is capable of high-

er output currents at lower duty cycles.

DO NOT SWITCH

WHEN WELDING

SP-135T

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 SP- 135T 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.
