KP3682-180 - Lincoln Magnum PRO 250LX 180-Degree Straight Barrel Assembly

Get Straight to the Weld with the Lincoln KP3682-180 Barrel

If you are running a Magnum PRO 250LX or 250LXGT spool gun, you know that sometimes a standard curved neck just doesn't give you the angle you need. The Lincoln Electric KP3682-180 is a 180-degree straight barrel assembly that swaps directly onto your existing gun, giving you a straight shot at your workpiece. This is the perfect solution for welding in tight channels, deep corners, or overhead positions where a curved neck might force your hand into an uncomfortable position or block your line of sight.

This kit comes ready to install with the barrel tube and the necessary retaining nut. It is built to handle the heat and current of the 250LX series, ensuring you don't lose any performance when switching configurations. The barrel is rated for wire sizes ranging from the fine .025" up to 3/64", covering the vast majority of aluminum and thin-gauge steel work you are likely doing with a spool gun. Because it is a genuine Lincoln part, the fitment is perfect—no cross-threading, no gas leaks, and no loose connections that cause arc instability.

Swapping out the barrel is a quick job that can be done right at the bench or even in the field. Having a straight barrel in your kit adds versatility to your spool gun, effectively turning it into a multi-angle tool. Whether your old barrel is clogged with spatter, bent from a drop, or you simply need the straight geometry for a specific project, the KP3682-180 gets your equipment back in top shape. Don't struggle with the wrong angle; equip your Magnum PRO with the right front-end parts for the job.

Reliability is key when you are under the hood. This barrel maintains the smooth wire feeding you expect from the Magnum PRO line. The internal liner path is optimized for soft aluminum wires, reducing the friction that leads to bird-nesting. Keep your welds clean and your downtime low with this essential replacement assembly.
