Orbital TIG Welding
A21 PRB / PRC / PRD 100 / PRD 160 / POC 12-60, Aristo Mech Tig 4000iw
The ESAB welding program for mechanised tube welding is based on the TIG welding method with a non-consumable tungsten electrode. To further improve weld quality and decrease costs, ESAB have developed microprocessor controlled power sources for orbital TIG welding, the Aristo MechTig 4000iw with control boxes Aristo MechControl 2 and 4.

A21 PRB Welding head is compact and easy to use as a result of its unique pincer action, which reduces setting-up times to a minimum. The welding head is positioned and secured around the tube with great accuracy in seconds. The PRB welding heads are available in three sizes for tubes with outer diameters of 17 to 170 mm.
