Lincoln Electric SP-100T manual Welding Capability, Limitations, Controls and Settings

B-2 OPERATION B-2

●No external shielding gas is required when used with Lincoln .035” (0.9 mm) Innershield NR®-211- MP electrode.

●Accommodates both 4” (100 mm) diameter and 8” (200 mm) diameter spools of wire.

WELDING CAPABILITY

The SP-100T is rated at 88 amps, 18 volts, at 20% duty cycle on a ten minute basis. CSA rated output at 62 amps at 20 volts at 20% duty cycle. It is capable of higher output currents at lower duty cycles.

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.

DO NOT SWITCH

WHEN WELDING

SP-100T

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- 100T 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.
