STH 160

Inverter-based, DC power source has a simple-to-use operator interface providing only the necessary controls in a compact machine.

Best-in-class TIG and Stick arc character istics for those demanding jobs.

Portable in the shop or at the job site — at 6.0 kg the shoulder strap allows the end user to easily move from location to location.

Built-in pulsing capabilities allow the operator to select from four fixed pulse frequencies to satisfy the application.

HF start for non-contact arc starting that eliminates tungsten or material contamination.

Dual fan technology. An optimised power source cooling system which enables the machine to operate at a lower temperature, thus increasing its performance and life cycle.

Thermal overload protection with indicator light helps prevent machine damage if the duty cycle is exceeded or airflow is blocked.

VRD function is a simple design that reduces the open-circuit voltage to 20 volts when the welding power source is not in use.
