Modular casing system for workstations in all kinds of environments. Gas- or water-cooled. DC or AC/DC. Flexible design: suitable for use both in production or as a mobile machine on the construction site or job. Portable or mobile on a trolley. Space-saving and lightweight design guarantees fl exibility and mobility.

You can stow consumables in the storage compartment on the newly designed handle and always have them ready-to-go.

Your Tetrix XQ is outfitted with an interface for remote controls as standard. There’s also a 7-pole digital interface for your ewm Xnet welding management software.

The large LED infobar with four unambiguous signal colours always shows you the current operating status of your TETRIX XQ.

To protect against damage, all connections are recessed into the casing, yet still conveniently accessible.

The protective cap protects against water, dirt and impact.

The new grille ensures that the airflow is diverted to below so that it doesn’t disrupt you or the welding process.

The completely new, robust machine feet also guarantee stability on uneven surfaces and protect against oil and salt water. They are perfectly suited for use in rough environmental conditions.

The protruding frame on the side around the control can be used to coil up the welding torch and hose package to keep the machine neat, tidy, and safe.
To keep your welding torch well cooled even under the heaviest loads, we developed the new COOL XQ cooling system. With excellent cooling capacity and integrated flow and temperature monitoring, it’s the perfect addition to your new TETRIX XQ. For those times when it takes a while. Air ducting of the TETRIX XQ operates in a targeted way, so only those parts which really need to be cooled are cooled. The sophisticated design minimises contamination, even in rough environments.
CAN BE USED WORLDWIDE.
In the multivolt version, the Tetrix XQ 230 puls with automatic adjustment of the mains voltage (110 - 120 V / 230 V) can only be combined with Cool XQ 40 MV.

The air escape is located on the side of the cooler to prevent contamination from the workplace entering the machine – no interruptions, for you or the welding process.

The water connections are recessed and optimally protected against damage.

Service-friendly design, e.g. access to centrifugal pump from exterior, without opening the casing.

You can easily check the filling level of the coolant from the indicator on the front, right next to the operating information.

The reusable stainless steel dust filter can be mounted without tools. It fits both your Cool XQ and your TETRIX XQ.

The power and control connections are located on the top of the cooler, so it connects perfectly to the TETRIX XQ.

The completely new, robust machine feet ensure stability of the stand even on uneven ground which make it perfectly suited for use in rough environmental conditions.

A water outlet screw is located on the front of the Cool XQ to make emptying the water tank easy, e.g. when cleaning the cooling circuit.
THE EWM XNET WELDING MANAGEMENT SYSTEM AND XBUTTON.
Xnet digitises your welding operations, making it the perfect addition to your new TETRIX XQ. This future-oriented welding management system organises production, planning, quality management, welding coordination personnel and administration. In this way, it decisively helps you improve efficiency, quality and documentation. This is Welding 4.0 – and our answer to Industry 4.0.
The Xbutton makes your TETRIX XQ even more reliable and a bit more “you”. You can easily transfer all the parameters from your personal welding plan and your specific menu settings to the machine.
With ewm Xnet, you get more done in the same amount of time. Paperless transfer of all relevant data directly to the workplace, fewer error corrections thanks to specified welding parameters and less unnecessary downtime thanks to timely maintenance notices simply allow you to work more efficiently.
XQ Series
DC or AC/DC? With or without cooling unit, site or workshop trolley?
You get exactly the Tetrix XQ you need for your welding tasks. As typical for EWM, the system is well thought out and every component is tested for tough everyday work.
Thanks to the variety of user-oriented accessories, the XQ series can be flexibly adapted to all challenges and applications.
