MIG Spool Gun SM300 Series

Successful aluminum welding requires a stable arc. A spool gun ensures a steady, consistent, and reliable wire feeding for soft wires like aluminum or brazing wires due to a short feeding distance. Spool gun improves the “feed ability” of aluminum wire by locating a small, 4-inch diameter wire spool (a one-pound aluminum spool) on a pistol-grip style gun. Using a spool gun saves considerable welding time while ensuring high weld quality. SM300Series Spool Guns are designed to feed wires which are difficult to feed through the standard MIG gun. These Guns can be used for stainless steel, flux-cored, and thin solid wires however they are most commonly used for aluminum and brazing wires measuring 0.03, 0.035, and 0.040 in. If you are going to use a MIG gun longer than 15 feet with solid wire or flux-cored measuring 0.023 or 0.030 in., Spool Gun is the best option. SM300 is a 300 A lightweight, well-balanced, dual groove drive roll, easy to set up, designed for easy and reliable aluminum wire feeding with a variety of CV power sources and engine-driven welders. The design of this spool gun reduces the maintenance and production time by allowing easy access to the drive rollers and performing routine maintenance without disassembling the gun.

Features :

  • Excellent and reliable for running 1-pound spools of aluminum MIG welding wire or 2-pound spools of mild steel and stainless steel. Silicon bronze MIG welding wire can be used too.
  • Processes: MIG (GMAW) for Aluminum wire size: 0.030″/0.035/0.040″/3/64″ (0.8/0.9/1.0/1.2 mm) MIG (GMAW) for Solid wire size: 0.030″/ 0.035″/0.040″ (0.8- 0.9-1.0 mm) and Flux Cored wire size: 0.030″/ 0.035″/0.040″/3/64″ (0.8- 0.9-1.0-1.2 mm)
  • Flexible spring guard strain relief protects the cable from wear by preventing kinking and abrasion and improves wire feed-ability.
  • Easy nozzle adjustment.
  • Ability to check remaining wire at a glance by a clear wire spool cover.
  • Easy adjustment of drive roll tension and pressure lever on the spool gun handle.
  • Heavy duty and metal made wire feeder mechanism.
  • Ideal for medium and heavy-duty industries.
  • 9-pin, metal made, durable control connector direct-plug to the welder.
  • Wire Brake system and a unique wire break keeps the spool under constant tension to prevent over-run of the wire.
  • Wire retainer device insures inadvertent de-reeling of the wire from the spool aided by the addition of a wire retention roller.
