Welding Capability; Limitations; Controls And Settings - Lincoln Electric SP-100T Operator's Manual

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.

LIMITATIONS

Arc Gouging cannot be performed with the SP-100T.
The SP-100T 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 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.
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).

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.
