Introduction - NewArc R4000 Operational Manual

1.2 Introduction

The R4000 and R5000 are advanced inverter power sources with outputs of 400 amps and
500 amps respectively. The CC/CV versions are suitable for MMA, TIG and MIG/MAG welding.
These inverter power sources are versatile, lightweight and portable. The advanced inverter design
provides a more stable and precise arc characteristic than conventional machines ensuring high quality
welding performance.
Due to the high efficiency and power factor these units provide energy and cost saving solutions.
Fabricated in a robust external casing this power source is extremely reliable in the most extreme
conditions
Features
• Inverter configuration provides a more stable and faster response in CC and CV control
resulting in more stable welding conditions
• Fabricated in robust external casing to withstand the most extreme environments
• Cooling on demand system minimizes power consumption and dust ingress
• The construction technique ensures minimal contamination of internal electronic systems
• Large overhead of voltage available for use with long interconnection cables.
