GENERAL DESCRIPTION

The SP-135 PLUS is a complete semiautomatic con- stant voltage DC arc welding machine. Included is a solid state controlled, single phase constant voltage transformer/ rectifier power source and a wire feeder for feeding solid steel electrode and cored electrode.

The SP-135 PLUS is ideally suited for individuals hav- ing access to 115 volt AC input power, and wanting the ease of use, quality and dependability of both gas metal arc welding or GMAW (also known as MIG welding) and the Innershield electrode process (self shielded flux cored or FCAW). The SP-135 PLUS is a rugged and reliable machine that has been designed for dependable service and long life.

RECOMMENDED PROCESSES

The SP-135 PLUS can be used for welding mild steel using the GMAW, single pass, process which requires a supply of shielding gas or it can be used for the self shielded, Innershield electrode process (FCAW). The SP-135 PLUS is configured for use with the GMAW (MIG) process as delivered from the factory.

●Reversible, dual groove drive roll. Drive roll will feed .023-.035” (0.6- 0.9 mm) diameter wire.

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

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

●Easy to change polarity.

WELDING CAPABILITY

The SP-135 PLUS, as shipped, is rated at 90 amps, 18 volts, at 20% duty cycle on a ten minute basis. It is capable of higher duty cycles at lower output currents.

LIMITATIONS

Arc Gouging cannot be performed with the SP-135 PLUS. The SP-135 PLUS is not recommended for pipe thawing.

CONTROLS AND SETTINGS

OPERATIONAL FEATURES AND CONTROLS

The SP-135 PLUS has the following controls as stan- dard: Power ON/OFF Switch, Voltage Control, Wire Speed Control, and a Circuit Breaker.

DESIGN FEATURES AND

ADVANTAGES

●Operates on 115 volt input

●Solid state output control.

●“Cold electrode” until gun trigger is pressed for an added measure of safety.

●Overload protection — incorporates both a thermo- stat and a circuit breaker.

●Quality wire drive with electronic overload protec- tion.

●Easy-to-set continuous range controls for precise setting of arc voltage and wire speed.

●Continuous voltage control.

●“Quick Release” idle roll pressure arm is easily adjusted.

Refer to Figures B.1a & B.1b.

1.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 welding output and wire feeder remain off until the gun trigger is pressed.

2.Voltage Control — A contin- uous control that gives full range adjustment of power source output voltage . Voltage can be adjusted while welding.

3.Wire Speed Control — Controls the wire feed speed from 50 – 400 in /min (1.3 – 10 m/min). The control can be preset on the dial to the setting specified on the SP- 135 PLUS Application Chart located on the inside of the wire feed section door. Wire speed is not affected when changes are made in the voltage control.
