EWM announces new TIG welding machine GERMANY-based manufacturer of arc welding technology EWM puts particular emphasis on improving user-friendliness when designing a new machine. The new controls of its TIG welding machine feature a 7” colour display and are well- arranged and intuitive to use. Welding tasks can be individually programmed and accessed again any time. The Tetrix XQ 230, which has an ergonomic and robust casing, is powerful and can be run directly from a single-phase 230V power socket, which makes it versatile in use. titanium. The spectrum of applications ranges from the food industry to aerospace, from the chemicals sector to mechanical and plant engineering and the metalworking trades. The new Tetrix XQ 230 also features Comfort 3.0 controls or the new Expert 3.0 controls with a high-resolution 7” colour display that shows all the parameter settings and flow diagrams. All functions are directly accessible and lots of illustrated instructions and quick menus provide additional support when operating the machine.

The controls can be precisely set with the ergonomic click wheel. EWM deliberately designed the machine without a touchscreen, to make it convenient to operate even while wearing welder’s gloves. The user can programme five individual welding tasks as favourites and access them simply at the push of a button.

The TIG welding machine also has a current of up to 230A and can be connected directly to a single-phase 230V power socket. It allows for continuous operation even on weak grids, with long mains leads or when in generator operation. Depending on the welding task, the user can choose from numerous TIG and MMA functions. Up to four pulse variants are available. The Tetrix XQ 230 is available in DC and AC/DC variants,

The new Tetrix XQ 230 offers a user friendly welding experience

so it covers a broad spectrum of applications. Different materials can be welded: from low and high-alloy steels to aluminium and aluminium alloys, all the way to nonferrous heavy metals and

ECOmax – Scarf HP1

Successful trials and on-going production usage, together with target customers and machine manufacturers have shown the ECOmax – Scarf HP1 blades achieve 8 - 10 times more of material removal than conventional specialized Scarf blades, on welded tubes with wall thickness up to 14mm. Further wear life tests and enhancements are planned to improve the blades performance even more. Using the ECOmax – Scarf HP1 blade is an enormous advantage for every application with heavy ID Scarf. This applies to single or twin-head tube cutting machines.

The ECOmax – Scarf HP1 circular saw blade is a further development of the Scarf blade and customized for cutting tubes and profiles with heavy ID Scarf on flying cut-off units. Previously, conventional blades were heavily damaged after only a few cuts because they cut the high strength weld bead inside the bottom of the tube. The service life of the blades was poor and the cost per cut is extremely high resulting in a cutting application that is not economical. Because of its new developed tooth form and cutting geo- metry, and in combination with a new proprietary coating, the ECOmax – Scarf HP1 saw blade is suitable for this appli- cation. This newdesign isworking successfully on single head machines as well as on twin saws with the simultaneous operation of two saw blades, to meet the customer’s requirements and decrease the cost per cut.
