Safety Considerations ELECTRIC ARC WELDING EQUIPMENT CAUTION : READ BEFORE ATTEMPTING INSTALLATION, OPERATION OR MAINTENANCE OF THIS EQUIPMENT 1-1 INTRODUCTION This equipment is intended for ultimate application by commercial/industrial users and for operation by persons trained and experienced in the use and maintenance of welding equipment. Operation should not be undertaken without adequate training in the use of such equipment.
Water-filling just below working level may substitute for inerting. Prohibited use. Never use a cylinder or its contents for other than its intended use, NEVER as a support or roller. A container with unknown contents should be cleaned (see paragraph above). Do NOT depend on sense of smell or sight to determine if it is safe to weld or cut. Locate or secure cylinders so they cannot be knocked over. Passageways and work areas. Keep cylinders clear of areas where they may be stuck.
A. Burn Protection Comply with precautions in 1-2. The welding arc is intense and visibly bright. Its radiation can damage eyes, penetrate lightweight clothing, reflect from light-colored surfaces, and burn the skin and eyes. Skin burns resemble acute sunburn; those from gas-shielded arcs are more severe and painful. DON’T GET BURNED; COMPLY WITH PRECAUTIONS. 1. Protective Clothing Wear long-sleeve clothing in addition to gloves, hat, and shoes.
Section A Installation Technical Specifications Wire Capacity .030" - .045" (0.6mm - 1.2mm) solid and hard wire .030" - 1/16" (0.8mm - 1.6mm) aluminum and cored wire Wire Speed 800 IPM (20.3 mpm) Max. at rated feeder Input Voltage (120VAC / 42VAC) Duty Cycle - 60% (All ratings are using Argon Gas) 225 Amps/25 Volts Air cooled standard Support Equipment Required • C.V. or C.C. Power Source of sufficient capacity for your needs. • Regulated gas supply and hoses.
Controls and Settings Potentiometer The laterally-positioned potentiometer is located in the lower end of the handle, providing up to 800 ipm with 3 3/4 turns. Micro Switch The micro switch assembly consists of the micro switch, and leads. Trigger Sensitivity The amount of trigger level travel can be shortened for a "quicker" or "more responsive" action. A more sensitive trigger lever is produced by reducing the gap between the trigger lever and the micro-switch lever.
table top, with the other hand give the Removal Tool a quick snap-turn in the CLOCKWISE DIRECTION. 3. Once the drive roll is loose, continue to spin drive roll in the clockwise direction to remove the drive roll from the gun. Figure 2 4. Install a new drive roll on the left-hand threaded shaft. The drive roll will self-tighten when it is feeding wire. Idler Roll Installation and Removal (Reference Figure 3) 1.

are the conduit, contact tips, gas cups, front body liners, wire guides, drive and idler rolls. A supply of these parts should be maintained on hand. The number of units in operation and the importance of minimal “down time” will determine to what extent spare parts should be stocked on hand. See the “Recommended Spare Parts List” for the most commonly replaced parts. If repairs do become necessary, qualified shop maintenance personnel can easily replace any part.
Section E Troubleshooting Trouble Cause Remedy 115/42 VAC Control fuse in Replace fuse. feeder/Control box blown. No wire feed at gun, feeder not operating, Micro-switch defective/not i.e. no slave motor being activated. or brake solenoid. Broken electrical cable. 24 VAC Control fuse in feeder/Control box blown. No wire feed at gun, feeder operating properly. Wire feeds, but welding wire is not energized. Wire feeds erratically. Wire feeds one speed only. Wire walks out of drive rolls.
Troubleshooting Guide Regardless of which gun or feeder used, all MK Products’ push-pull guns operate on the same principle. The slave motor in the feeder runs at a fast, constant speed, but has very low torque. It is always trying to feed more wire than the gun motor wants, and when the motor gets all it wants, it slows the slave motor, preventing a bird’s nest. Because of the low torque produced by the slave motor, a brake system is used to prevent wire overrun rather than tension.
