Advanced Programmable Multi-Process Welding Arc Controller

Tri Tool’s AdaptARC mechanized orbital pipe and tube welding machine is designed to facilitate every aspect of the welding procedure. Use AdaptARC’s OrbitMASTER controller to modify short arc for open root welding and eliminate the time-consuming hot pass.

Chaining and linking programs together allows the next program to begin at the end of the previous program. You can create a program that will put the root, hot pass, fill layers, and cap without stopping, shortening overall automated welding time.

You can also loop programs to allow the same program to repeat multiple times allowing repeat processing of across similar characteristics to continue uninterrupted.

Reduce technical support costs by operating an automated welding machine with full digital controls, eliminating frequent calibration required on other systems, saving precious time on the job.

Capabilities of this orbital welding machine controller include:

  • Can Perform Pulsed or Non-Pulsed GTAW and/or GMAW, as well as FCAW
  • Ideal for Non-Typical Seams Including Multi-Axis Type Joints, Angles, & More
  • Automatic Guidance that Allows Hundreds of Points
  • Precision Seam Tracking and Waveform Generation (GMAW) for Reduced Spatter and Smoke

The ORBITMASTER® Weld Controller has been designed to provide the welder with all of the advantages and benefits that digital control can introduce to the welding process. This new multi-process controller can perform pulsed or non-pulsed GTAW and/or GMAW, as well as FCAW, for maximum selectivity. Switch from GTAW to SMAW-P for the ability to control heat inputs needed for special metal alloys or when FCAW wire is not available and high deposition rates are needed with available solid core wire. Along with conventional bevel joints, the programmable controller is ideal for non-typical seams including multi-axis (saddle-on) type joints, angles, curvatures, indentations, and protrusion welds.

Automatic guidance capability provides control and position recording along a path (from hundreds of points) for repeatable precision. Programmable control is provided for torch to workpiece Arc Voltage Control (AVC), oscillation, travel, wire feed, coolant recirculation and power source/AVC sensing.

Other unique advantages of the ORBITMASTER® controller include the modified short arc that permits “open root” GMAW-S on a standard “off the shelf” large bore pipe fittings using foundry supplied bevels.

This ideal welding equipment is comprised of the new ORBITMASTER® Weld Controller with its remote control pendant, a matching commercial power supply, the DualARC® Multi-mode Weld Head with dedicated guide tracks, and a coolant re-circulator.

New Weld Program Editor

Create, modify, and print AdaptARC weld programs on any compatible PC computer

In addition the ORBITMASTER® has the capability to create custom weld programs using the Weld Program Editor (WPE) software. This software is a remote programming application for creating, modifying, and printing AdaptARC weld programs on any compatible PC computer. The WPE graphical interface is user-friendly and provides the same detail and flexibility as the AdaptARC console with the added convenience of working offline from the equipment. Weld programs can be transferred between the AdaptARC console and the WPE software with a USB thumb drive.

DualARC – Multi-Process Weld Head for Both Precision Orbital and Linear Welding

The new DualARC Weld Head is a breakthrough in mechanized orbital tube welding. Its new design permits rapid change over from GTAW to GMAW. Automatic steering control provides precision non-symmetrical weld paths for saddle and other special shapes, and automatic rewind and bead placement.

The weld head traverses on modular guide tracks for accurate and solid positioning, optimal for narrow groove orbital welding. The DualARC Weld Head is perfectly matched to the OrbitMASTER controller for orbital welding system applications.

  • Rugged Construction for Accuracy
  • Rapid Process Switching Without Removing Head From Track
  • Automatic Steering Control
  • Automatic Rewind & Bead Placement

Designed with Versatility in Mind

The new DualARC® has been designed from the ground up for use with the AdaptARC automated welding machine to provide ease of user maintenance with “off the shelf parts” that can be changed in-place with common tools. Rugged construction delivers the precision and repeatable accuracy so critical for the tight tolerances of the orbital welding process.

Trust Tri Tool to deliver the best in mechanized orbital tube welding systems.

New Optional Hot Wire Kit

The Hot Wire Kit is an optional accessory designed to expand the capabilitiy of the OrbitMASTER Weld Console and DualARC Weld Head for GTAW processes. The Hot Wire Kit applies an AC current to the weld filler wire as it travels towards the weld puddle, and provides significant benefits and time savings compared ot cold wire GTAW processses. Hot Wire GTAW allows for an increased filler wire deposition rates, reduction of the heat affected zone through lower arc power levels, and increased weld pool control during high energy input processes.


The DualARC® can be configured for special applications, such as ID cladding (shown right). In this case, a video camera was installed for remote monitoring of the weld. The ORBITMASTER® performed Pulse Spray Transfer for exceptional cladding and the programmable weld controller can reverse the travel direction for accurate interrupted openings, producing repeatable accuracy. This unique capability delivers uniform and consistent deposition of metal for critical pipe maintenance procedures.

Frequently Asked Questions


If you can’t find the answer that you are looking for, please use our
online form and we will be glad to get your questions answered.

For both TIG and MIG processes, what bevel configurations will work for each?

J-Bevel is acceptable for both Tig and Mig. V-groove is recommended for Mig.

Can the orbital welding machine weld on all positions?

Yes, it can weld on all positions.

For the MIG process, the welding system can do uphill welding including root pass, but can it do downhill as well?

The orbital welding machine can weld 360 degrees with GMAW.

Can the system do FCAW process?

Flux Core (GMAW) can be done with this system.

Can the orbital welding system do Hot Wire welding?

The machine can be configured for Hot Wire welding with an additional kit.

How many guide tracks (rings) will I need?

It depends on the sizes of the pipes you are welding. One ring can mount up to 3 different pipe sizes.

Can the welding system weld both Carbon Steel and DSS?

Yes, both materials are able to be welded by the AdaptARC orbital welding machine. Welding on high alloy pipes can also be achieved, performed quickly and with 100% acceptance.

What is the smallest pipe or tube diameter and wall thickness recommended?

The smallest size track that the head can use is the one for 6″ pipe. All welding system track, including the 6″ size can be mounted on pipe two sizes smaller. That makes 2″ the smallest pipe size for the system. The limitation on how small the wall thickness can be is the pipe needs to be stiff enough to tighten the track enough to securely hold the welding head without distorting the pipe.

What HI-LO / out of roundness can the system take without doing any machining?

The machine can weld Hi-Lo and pass an x-ray, but will have to be reviewed on a case by case basis.

In the event my ORBITMASTER® controller requires repair, how easily can it be fixed?

Our AdaptArc technicians will coordinate with you to diagnose a problem with your ORBITMASTER® controller. A determination will then be made if the repair can be completed by you or the controller will need to be returned to us for repair. The design of the system lends itself to on-site repairs. For instance, if it’s determined to be a board issue, you can simply replace the old board, in-situ, by removing a few screws, sliding out the old board, and replacing it with a new board provided by Tri Tool.

Which power supply comes with the orbital welding machine and what are the voltage configurations? Is the welding system compatible with other power supplies?

The Miller XMT450 CC/CV is currently supplied with the welding machine. The system’s input power requirements are either 230VAC, 51A, 60Hz, 3-phase or 460VAC, 28A, 60Hz, 3-phase. The welding system is compatible with other power supplies. Please contact your representative for more information.

Are the consumable parts used in the AdaptArc custom and difficult and expensive to obtain?

Just as Tri Tool supports customers who have acquired one of our pipe cutting and beveling tools with high-quality parts, AdaptArc system owners will be able to acquire consumables quickly and economically directly from Tri Tool or one of its authorized distributors; at your option, you may also acquire consumable parts that are manufactured by world recognized manufacturers from your local welding supply distributor.

What automatic welding programs come standard with AdaptArc and how do I acquire programs for other applications?

AdaptArc currently comes standard with a wide variety of welding programs for different applications such as 6” carbon steel pipe with GTAW from start to finish and GTAW/GMAW-P for 12” carbon steel pipe. The orbital welding system is also supplied with a detailed set of user-friendly programming instructions to help your welder program the system for their unique application. While custom programs can be ordered from Tri Tool you have the flexibility to develop your own weld procedures.

Many companies offering automatic orbital welding machines claim to be flexible; what is an example of a feature unique to AdapArc's welding system that provides true flexibility?

It is the only true DUAL HEAD welding system in the welding industry that can switch between GTAW and GMAW-P/FCAW in only a few minutes with no need to remove the weld head from the track.

With good maintenance practice, what would be the life expectancy of the equipment?

The heavy wear components, such as drive rollers that move the head around the track, have proven to be extremely durable. It is expected that, other than for the replacement of normal consumable items, the welding system should provide hundreds of hours of operation prior to servicing.

Besides the applicable track to use AdaptArc’s unique flexibility to weld on pipe from 2” – 10’ diameters; what accessories may be required?

You may be required to purchase an additional length of umbilical power cord depending on diameter.
