ARCCAPTAIN 100A MIG Gun for Lincoln Magnum 100L: specs and fit

This ARCCAPTAIN MIG gun is a replacement torch (sometimes called a stinger) for the Lincoln Magnum 100L, part number K530-6. It is rated at 100 amps and has a 10-foot (3 m) cable. If the original gun on a compatible Lincoln machine is worn out, damaged or missing, this is an accessory made to take its place.

What a MIG gun does

In MIG welding, the gun carries welding current, shielding gas and wire from the machine to the work. A trigger starts the wire feed and the arc. Because the gun is handled constantly, its cable, trigger and contact tip wear out before the welder does, which is why replacement guns exist.

What it fits

ARCCAPTAIN says it is fully compatible with the Lincoln Magnum 100L (K530-6). The listing names these Lincoln machines as commonly used with that gun:

• Easy-Core 125, 140 and 180
• MIG Pak 140 and 180
• Power MIG 140C, 140T, 180C and 180T
• Pro-MIG 140, 175 and 180
• SP-140T and SP-180T
• Weld-Pak 125, 125HD and 140HD

Compatibility is the single most important thing here. Check your own machine's model and its gun connection against the part number before you decide.

Cable and handle

The brand describes a copper cable meant for good conductivity and long life. The handle is ergonomically shaped, with a trigger that ARCCAPTAIN says gives easy control and a positive response. A 10-foot cable gives a reasonable working radius around the welder without needing to move it.

Tips included

The gun comes fitted with a .030-inch contact tip, and .035-inch tips are in the package. The tip should match the wire diameter you use. A tip that is too large or too worn can make the arc erratic, so it helps to keep spares.

Amperage limit

The 100A figure describes what the gun is built to carry. Compare it with the maximum output of your welder and the duty cycle in your manual. Follow the manual for installation, shielding gas and wire setup.

Who it suits

It suits owners of the listed Lincoln welders who need a spare or replacement gun. It is a part rather than a complete welder, and it does nothing without a compatible machine.

What to check before you buy

• Model match: compare your machine against the list and the K530-6 part number.
• Connector: confirm the gun's connection matches your wire feeder.
• Wire size: check that the supplied tips match the wire you use.
• Cable length: decide whether 10 feet is enough for your workspace.
• Spare parts: consider which consumables, such as nozzles and liners, you may also need.
