●No external shielding gas is required when used with Lincoln Innershield .035” (0,9 mm) NR®-211- MP electrode.

●Spindle accommodates both 8 in. (200 mm) diame- ter and 4 in. (100 mm) diameter spools of wire.

WELDING CAPABILITY

The SP 170-I is rated at 125 amps, 20.25 volts, at 25% duty cycle on a ten minute basis. It is capable of higher output currents at lower duty cycles. Actual welding outputs will range between 30 and 175 amps for the recommended processes.

LIMITATIONS

Arc Gouging cannot be performed with the SP 170-I. The SP 170-I is not recommended for pipe thawing or TIG welding.

CONTROLS AND SETTINGS

Refer to Figures B.1a (Items 1 thru 4)

	1. Power ON/OFF Switch — When
	the power is on the fan motor
	will run and air will be exhaust-
	ed out the louvers in the front of	ON
	the machine. The welding out-	ON
	put and wire feeder remain off
	until the gun trigger is pressed.
	2. Voltage Control — A 5-position	OFF
	tap selector switch gives full	OFF
	tap selector switch gives full
	range adjustment of power
	source output voltage. Do not
	switch while welding.

6. 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.

3.Wire Speed Control — Controls the wire feed speed from 50 – 400 in/min (1.3 – 10.2 m/min). The control can be preset on the dial to the setting specified on the SP 170-I Application Chart located on the inside of the wire feed section door.

4.Temperature Light — Indicates thermostat has cut the output. The fan will be running. Thermostat resets automatical- ly.

5.Circuit Breaker – Protects machine from damage if maximum output is exceeded. Button will extend out when tripped (Manual reset).
