K387 - Lincoln Tandem Arc Mounting Framework for NA Series Feeders

Simplify Your Heavy Fabrication Setup

When you are setting up for a big job that requires the speed and deposition of tandem arc welding, the last thing you want to do is waste time fabricating your own mounting brackets. The Lincoln Electric Tandem Arc Framework Assembly (K387) is the professional solution to getting your automatic wire feeders up and running quickly and securely. Designed specifically for the heavy-duty demands of industrial welding, this framework takes the headache out of aligning dual wire feeders. Whether you are running Submerged Arc on heavy plate or high-speed automated MIG, this assembly provides the rock-solid foundation your equipment needs.

The K387 is built to hold two Lincoln NA-4F, NA-3SF, or NA-5SF wire feed heads side-by-side. It comes right out of the box with everything you need to mount it directly to a Lincoln TC-3 Carriage, turning a standard travel carriage into a tandem arc powerhouse. If you are working with a custom gantry or a shop-built fixture, the framework adapts easily to those setups as well, giving you the freedom to weld how you need to. It even includes the insulation hardware, so you don't have to worry about electrical interference between your heads or shorting out to the frame—a common issue when rigging up homemade mounts.

Stability is key to a good weld, especially when automation is involved. A shaky mount means a wandering arc, and a wandering arc means rework. The Lincoln Tandem Arc Framework is constructed from durable materials that resist vibration and hold your settings true, pass after pass. It allows for the precise positioning adjustments you need to dial in your lead and trail wires for that perfect bead profile. Instead of struggling with makeshift setups, trust the K387 to hold your gear steady so you can focus on monitoring the weld and keeping production moving. It is a rugged, practical upgrade for any shop looking to maximize their automated welding efficiency.
