Orbital weld heads with digital technology eliminate need for calibration

Magnatech LLC has introduced a full line of enclosed autogenous orbital weld heads that incorporate digital encoder drive motors and eliminate the need for calibration.

A patent-applied-for over-close collet clamping system and full-exchange water cooling system allow for true 100-percent duty cycle, the company reports. Five models cover tube sizes from 0.125 in. (3 mm) OD to 6.625 in. (168 mm) OD.
