Take the Headache Out of Long Welds

If you have ever run a sub-arc tractor or a column and boom on a 40-foot beam, you know the struggle: staring at the flux pile or the arc for hours, hand hovering over the cross-slide joystick, making tiny adjustments every few seconds to keep the weld in the joint. The ESAB GMH Joint Track System W/Panel is designed to do that job for you, so you can focus on the weld parameters and overall quality rather than fighting with alignment.

This system acts as your "autopilot" for welding. Once you set up your torch and engage the tracker, the GMH system takes over. It feels the joint (using a probe) and automatically moves the torch up, down, left, or right to stay perfectly centered. This is a game-changer for long seams on tanks, pipes, or structural steel. It means you don't have to worry about the part warping as it gets hot or if the fit-up isn't 100% perfect down the line. The tracker compensates for those imperfections instantly, far faster and more accurately than a human operator can over a long shift.

The "W/Panel" in the name means this unit comes with the control box you need right at your fingertips. The panel is straightforward and rugged—built to survive in a shop full of grinding dust and welding fume. You can easily adjust how sensitive the tracker is. If you are welding over tack welds, you can adjust the settings so the machine doesn't jump or jitter when it hits a bump. It smooths out the travel, resulting in a professional-looking bead with consistent penetration.

Using the GMH system also significantly reduces rework. Because the machine ensures the arc is always in the root or exactly where you want it on the sidewall, you avoid common defects like lack of fusion or off-center beads. It turns a stressful, high-fatigue job into a manageable, monitoring role. Whether you are running heavy sub-arc or high-amperage MIG, this tracking system is the extra set of hands you need to guarantee every foot of weld meets code requirements.
