Recommended Applications
  • Aluminum MIG welding: The Magnum SG spool gun eliminates the bird-nesting and feed problems inherent in pushing aluminum wire through a long MIG gun liner. Wire feeds from a 1 lb spool mounted at the gun head, keeping the feed path short.
  • Soft-alloy and flux-cored wires: Any wire that tends to kink or deform in a push-only cable — magnesium, silicon-bronze, and soft stainless variants — benefits from the spool-at-gun design.
  • Long-reach production and repair work: With a 25 ft cable, you can position the welder or wire feeder out of the work zone while still reaching overhead joints, automotive bodywork, and marine fabrication with consistent arc performance.
  • Shop and field use: The spool gun format keeps the wire dry and protected from contamination; ideal for aluminum boat repair, HVAC fab, and trailer manufacturing where cleanliness and portability matter.
Compatibility

The K1809-1 kit is designed for use with Lincoln Electric wire feeders and MIG welders that support the Magnum SG spool gun interface via the included adapter cable. Typical compatible platforms include Lincoln wire feeders in the LN and Powerfeed series equipped with the appropriate gun receptacle. The adapter cable in the kit bridges the feeder’s standard output connector to the Magnum SG gun plug, so no separate adapter purchase is required.

Before ordering, confirm your welder or feeder model accepts the Magnum SG adapter. If you are unsure of compatibility, contact WeldingMart — our team stocks the full Lincoln Electric spool gun catalog and can cross-reference your machine serial number.
