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
• 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.
