DESCRIPTION
This equipment has been designed with inverter technology which allows the allows the construction of a lightweight and portable MMA Inverter
DC welder machine which can be used in a wide variety of general welding applications and environments.
The equipment uses the latest pulse width modulation (PWM) technology together with an Insulated Gate Bipolar Transistor (IGBT) Power Module
to deliver a consistent current output and reliable welding arc with relatively low power consumption.
DC Output
This equipment has a DC output and when combined with the correct type of electrode it is suitable for welding alloy, non-alloy steels, stainless
steel and cast iron. Electrodes up to 3.2mm can be used with ease.
Generator Friendly
The welder is able to cope with fluctuations in power input of +/-10% making it compatible for use with a wide range of modern generators.
Electrode Current Protection
If the electrode touches the workpiece for longer than 1.5 seconds the welding current will drop to the minimum current level (while arc force is
maintained with the MMA operation).
