The HELIX® M85 is the first next generation orbital welding head. It incorporates digital capabilities in an intuitive ergonomic design, bringing the best in class for all of your orbital welding needs from FCAW to Hot Wire Laser welding and everything in between.

The platform was designed around the advanced / multi-process capabilities of the Power Wave. It can weld a variety of standard welding process and is capable of utilizing some of the latest ground breaking welding process recently invented. As process change over time and new capabilities are invented the HELIX® M85 can grow with your needs.

Major upgrades can be simply accomplished with limited technical capability due to the digital nature of the weld head. To add onboard wire feeding capability only a simple Allen wrench is required and everything else just plugs in-line with the common control cable. Even when a weld head gets damaged all that is needed is to install a new weld head on the system and to cycle power. No more tedious calibration and manual verification before the replacement equipment can be put into service.

The HELIX® M85 removes the steep learning curve that is required with most other orbital equipment due to simple design efforts. All of the motors and harnesses are packaged inside the weld head, reducing the visual confusion when working around the equipment. Care has been taken to highlight in Red the human touch points of the weld head, so that operators easily know where adjustments can be made. And you can leave your extensive tool chest at home when working with the equipment. Day to day operations can be completed with minimal tools.

One person can easily mount and dismount the weld head to the patented track ring. This is achieved by the relatively low weight of the weld head and key mechanical capabilities built-in. Ease of mounting the weld head onto the track is accomplished by using two different wheel sizes in the weld head, allowing the weld head to properly engage the track ring and automatically adjust for different track ring diameters. Other solutions require complicated operator alignment efforts to properly mount and align the weld head to their track.

All of this is achieved while still providing rugged and reliable welding equipment that you have come to expect from the welding experts of Lincoln Electric.


The HELIX® M85 weld head is capable of GMAW and FCAW weld travel speeds, but has the precision and accuracy needed for GTAW, Hot Wire GTAW, and Laser operations. Repeatable welds and operations are the key in orbital welding and the APEX® / HELIX® system was engineered for exactly that. To further advance repeatability, the HELIX® M85 weld head incorporates an inclinometer to allow automatic weld parameter changes based upon the torches position on the pipe.


Optional On-board wire feeders are available for GMAW / FCAW and GTAW welding applications. These wire feeder modules and other available modules make switching between different processes and applications quick and easy. All of this is achieved while still providing rugged and reliable welding equipment that you have come to expect from the welding experts of Lincoln Electric.
