GENERAL DESCRIPTION
The SP-135T is a complete semiautomatic constant- voltage DC wire feeder / power source arc welder. It has been designed for workshop, hobby, automotive and light maintenance. Included is a tap-switch con- trolled, single phase constant voltage transformer / rectifier power source and a wire feeder welding gun for feeding .023 - .025” (0.6 mm) through .030” (0.8
mm)solid steel electrode. An optional kit is available for feeding .035” (0.9 mm) Innershield® NR-211-MP flux-cored wire.
The SP-135T is ideally suited for individuals having access to 120 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-135T is a rugged and reliable machine that has been designed for dependable service and long life.
RECOMMENDED PROCESSES
The SP-135T can be used for welding mild steel using the Gas Metal Arc Welding (GMAW or MIG, Metal Inert Gas) single pass process, which requires a sup- ply of shielding gas, or the flux-cored arc welding (FCAW) process using Innershield® electrode wire. The SP-135T is configured for use with the GMAW process as delivered from the factory.
OPERATIONAL CONTROLS
The SP-135T has the following controls as standard: Control Power ON/OFF Switch, Voltage Control, Wire Speed Control, Trigger Switch, and a Circuit Breaker.
DESIGN FEATURES
●Operates on 120 volt input
●“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.
●“Quick Release” idle roll pressure arm is easily adjusted.
●Reversible, dual groove drive roll. Drive roll will feed .023 – .025” (0.6 mm) and .030" - .035" (0.8 - 0.9 mm) diameter wire.
