The PowerARC 160i STH is a completely new model that succeeds the PowerARC 160STH.  This model retains all the functionality of the older model, but does so with a more reliable and compact digital design.

The features that made the PowerARC 160STH popular are still there in this new model, but the unit features better TIG performance and now can be fitted with the long-life, high quality NOVA foot pedal.  An IGBT inverter design is still at the heart of the unit, but the new digital control simplifies internal circuitry and reduces maintenance and improves long term serviceability options.

For people seeking a basic DC TIG and Stick welder, this unit has what you need.


PLEASE NOTE: Everlast Welders Australia strongly recommends the use of a 15A RCD box between the machine and wall socket during use. To achieve the maximum performance out of your Everlast Machine please ensure your current breaker and wiring/socket setup at your place of use is sufficient enough to achieve this. For example you may be required to upgrade your breaker to a 32A dedicated circuit to suit, therefore allowing you to achieve your machines full duty cycle. If in doubt please contact your local licensed electrician for more info prior to purchasing and please see terms and conditions/warranty for more information.
