●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.

●Accepts optional Spot/Stitch Timer Kit.

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 170 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,

B.1b and B.1c.

1.Power ON/OFF Switch — When the power is on the fan motor will

run and air will be exhausted out

ON

the louvers in the front of the

 

machine. The welding output and

 

wire feeder remain off until the gun

 

trigger is pressed.

 

OFF

2.Voltage Control — A 5-position tap selector switch gives full range adjustment of power source output voltage. Do not switch while

6.Optional K695-1 Spot/ Stitch Timer Kit Controls (see ACCESSORIES section) - If present, replaces Blank Panel Assembly located on the center panel inside the case door:

Mode Switch - Selects between Spot, Stitch, or Seam (normal welding) mode. Spot mode welds for an adjustable length of time (set by Time Control; see below) and then stops, whenever the gun trigger is depressed and held. Stitch mode cycles between weld- ing and not welding for an adjustable length of time (also set by Time Control) while the gun trigger is depressed. In Seam mode the machine will weld continuously while the gun trigger is depressed. Releasing the gun trigger in any of the three modes will interrupt welding immediate- ly.

Time Control - In Spot mode, controls spot mode ON time between approximately .25 and 4.0 seconds. In Stitch mode, controls stitch mode ON time and OFF time simultaneously between .25 and 4.0 seconds each. This control is deactivated while in Seam mode.

7.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.

3.Wire Speed Control — Controls the wire feed speed from 50 – 400 in/min (1.3 – 10.2 m/min). The con- trol 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 automatically.
