This CSIRO-designed and patented welding torch is suitable for both high current melt-in mode and keyhole mode operation. It features extensive water-cooling of both the torch barrel and the gas shroud, and is able to provide excellent arc stability at currents as high as 1000 amps. A selection of collets and contact tips is available, depending on application. The standard package allows for choice between 3.2mm and 6.4mm electrodes; 4.0 and 4.8mm electrodes can also be accommodated.

This new torch has been designed specifically for use in the keyhole mode. Features include very low internal resistance, well-defined electrical and thermal pathways, excellent cooling, and expanded gas coverage. In addition, the torch has been designed to accept a range of trailing shields when the application requires. The torch can be adapted to run in the melt-in mode simply by changing the tungsten electrode and the contact tip. The standard package includes torch, spare shroud and contact tip, tungstens and gas and water lines. |

Ultratig’s technology package is centred on its technology platform. This unit incorporates water cooler, and high voltage arc initiator, and integrates control of the other essential services: gas supply, welding power supply. Its PLC provides the versatility for either manual, automatic or remote control of the process. In addition it has been configured for easy upgrading for future developments such as automatic keyhole detection, and complete turn-key operation utilizing feedback control of the welding parameters. This unit together with one of the available torch packages is the recommended requirements for implementing the process.
Ultratig produces a range of trailing shrouds for both plate and pipe work. These shrouds are designed to be used withth Ultratig Keyhole Torch. Please contact Ultratig to discuss your requirements.
Ultratig is developing back-purge systems that integrate with the technology platforms. When correctly applied back-purging can dramatically improve root-bead characteristics and considerably expand the operating window of the process. Please not that standard back-purging techniques are not suitable for keyhole processes, and can result in unstable operation and weld defects.
