Introduction - NewArc R4000cc Operational Manual

1.2 Introduction

These heavy duty MMA D.C inverter power sources have been designed using the latest developments
in power electronics. Electronic parts are enclosed in a separate sealed compartment for protection from
the environment.
This portable, versatile inverter power source responds to changes in the welding arc much faster than
conventional machines resulting in a more stable and controllable weld pool.
Due to the high efficiency and power factor these units provide energy and cost saving solutions.
Features
