GENERAL DESCRIPTION
The WELDMARK 135 PLUS is a complete semiauto- matic constant voltage DC arc welding machine. Included is a solid state controlled, single phase con- stant voltage transformer/ rectifier power source and a wire feeder for feeding solid steel electrode and cored electrode.
The WELDMARK 135 PLUS is ideally suited for indi- viduals having 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 WELD- MARK135 PLUS is a rugged and reliable machine that has been designed for dependable service and long life.
RECOMMENDED PROCESSES
The WELDMARK 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 WELDMARK 135 PLUS is con- figured for use with the GMAW (MIG) process as delivered from the factory.
●Reversible, dual groove drive roll. Drive roll will
●Accommodates both 8” (200 mm) diameter and 4” (100 mm) diameter spools of wire.
●No external shielding gas is required when used with Lincoln Innershield .035” (0,9 mm)
●Easy to change polarity.
●Accepts optional Spot/Stitch Timer Kit.
WELDING CAPABILITY
The WELDMARK135 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 out- put currents.
LIMITATIONS
Arc Gouging cannot be performed with the WELD- MARK 135 PLUS and it is not recommended for pipe thawing.
CONTROLS AND SETTINGS
OPERATIONAL FEATURES AND CONTROLS
The WELDMARK 135 PLUS has the following controls as standard: Power ON/OFF Switch, Voltage Control, Wire Speed Control, and a Circuit Breaker.
DESIGN FEATURES AND
ADVANTAGES
●Operates on 115 volt input — no special wiring required.
●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.
●
●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 welder 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.
