The Lincoln Electric MIG Conversion Kit K610-1 converts compatible Lincoln flux-core (gasless) MIG welders to gas-shielded MIG welding at 115/120V — adding the gas solenoid, regulator, and hose hardware needed to run solid wire with CO2 or mixed-gas shielding, expanding the welder's material and application range.

| Application | Converting Lincoln flux-core-only MIG welders to gas-shielded MIG (GMAW) capability |
- Gas MIG upgrade for flux-core-only machines: Convert a Lincoln flux-core MIG welder to full shielded MIG operation, enabling you to weld with solid ER70S-6 wire and CO2 or 75/25 Ar/CO2 shielding gas for cleaner welds on thinner material.
- Thin steel and automotive sheet: Gas-shielded MIG with solid wire produces significantly less spatter and smoother beads on thin sheet metal compared to flux-core, making it the preferred process for auto body and light fabrication work.
- Shop and garage welding upgrades: A cost-effective way to expand the capability of an existing 115V Lincoln machine without purchasing a new welder.
- Aluminum and stainless compatibility: Gas-shielded MIG is required for aluminum and stainless steel welding; this kit provides the necessary shielding gas system for those applications (appropriate wire and drive rolls also required).
The K610-1 is a Lincoln Electric OEM conversion kit designed for 115/120V Lincoln flux-core MIG welders, including the Lincoln Weld-Pak 100. Verify your specific machine model against Lincoln's compatibility list — not all Lincoln 115V machines are designed to accept the K610-1 kit, and installing a conversion kit on an incompatible machine will not work correctly.
The K610-1 is the 115/120V version. If you have a 208/230V Lincoln MIG welder (such as machines designed for the K610-2 kit), see the Lincoln MIG Conversion Kit K610-2 instead.
