The robots are designed specifically for arc welding: one unique feature is that all the media needed for welding are directed first through the main axis and then through the hollow shaft into the wrist axis, allowing the welding torch to complete two full turns. The result is a significant advantage in terms of accessibility to tight work pieces and in circular seams.

Perfection of arc means that the robots are working with 6, 7 or 8 rotary axis in a solid aluminium cast construction, mounted either upright or in suspended position.

Axis arrangement
Not only the drive media of the robot run through axis 1 in the RTE robot system, but also the welding media such as the cooling hoses, gas hoses, cable conduit hoses and water cooled cable for the welding current connection, as well as the control cable for the wire feed.

To keep the robot and the welding equipment slim at the base, the wire feed is integrated into axis 1 and protected from environmental influences with a cover.

An additional axis is provided for any application that requires a special range of motion – the rotating base. This is entirely integrated into the kinematic chain of the robot control system and, together with axis 1, permits an enormously expanded sphere of motion. The maximum work zone radius of 5200 mm can be extended as needed with the external rotation and linear axes.

Multipurpose igm robots
Welding, cutting, bevelling and more – multitasking by igm.

igm robots can do everything: Beside of welding they are also able to cut, bevel, move, pre-heat and more. In this case only the tools need to be exchanged. A real multitasking robot!.
