Improved access for welding with Fronius’ slim gas nozzle

imageedit 2 7905884820Austria-based Fronius International GmbH, provider of welding technology, photovoltaics and battery charging technology, has developed a new torch body for robotic welding devices, to provide improved access to components

According to Fronius, the MTB 350’s gas nozzle has a diameter that is 20 per cent smaller than conventional torches.

Owners of the Fronius TPS and TPS/i robotic welding devices can retrofit the new machine torch body (MTB) 350. The gas nozzle’s diameter is now only 20mm, as opposed to the conventional 25mm. This means the welding torch can reach the interface more easily, even when working with challenging component geometries.

Fronius said that the new torch body is available in various geometries (22°, 36° and 45°). The MTB 350 is also available in the ‘Asian Style‘ variant, with the longer torch body being suited to the typical design of robotic welding torches used in Asia.

“Despite the slim gas nozzle, the new torch body enables a high duty cycle at maximum output, at 350 A when using pure CO2, the welding torch achieves a duty cycle of 60 per cent, i.e. the arc can operate for six minutes out of 10,” said the company.

Fronius further added, “At 300 A, the torch can weld without interruption. If mixed gas is used, the MTB 350 can achieve a 100 per cent duty cycle at 250 A and 60 per cent at 300 A.”
