TOTAL 400A MMA Inverter Welding Machine TW24003

The TOTAL 400A MMA Inverter Welding Machine is designed for stick welding in metal fabrication, maintenance and repair applications. Featuring IGBT inverter technology, LED displays and adjustable current and arc-force controls, it provides a practical welding setup for suitably equipped workshops.

With a 400A advertised output rating and a specified 380–400V AC, 50/60Hz supply, this machine is suited to installations with the correct electrical power provision.

MMA Stick Welding

The machine uses Manual Metal Arc (MMA) welding, commonly known as stick welding. It works with compatible coated electrodes for joining suitable metals, making it useful for fabricating gates, frames, brackets and other steel components.

Choose the electrode type and welding current according to the material, joint and electrode manufacturer’s instructions.

IGBT Inverter Technology

The IGBT inverter system electronically controls welding power. This design supports adjustable output in a compact machine format, making it convenient for workshop fabrication and repair tasks.

Adjustable Welding Current

The front-mounted current control knob allows you to set the welding output for the electrode and job. The LED displays provide visible operating readings to assist with setup and monitoring.

The usable current range, electrode capacity and duty cycle should be checked against the machine’s full specifications.

Adjustable Arc Force

The arc-force control allows adjustment of the arc response when the electrode approaches the workpiece. This helps maintain the arc during short-arc welding and can reduce the tendency for the electrode to stick.

Anti-Sticking Function

The anti-sticking feature helps reduce current when an electrode sticks to the workpiece, making it easier to release and reposition the electrode.

Voltage Reduction Device

The machine includes VRD functionality, designed to reduce the open-circuit voltage when welding is not taking place. This adds a protective feature while the machine is idle; normal electrical safety precautions remain essential.

Workshop-Friendly Construction

The metal housing features ventilation openings for cooling airflow. A top-mounted handle assists with repositioning, while clearly marked positive and negative terminals provide welding lead connection points.

Suitable Applications

• Gate and grille fabrication.
• Steel frame and bracket assembly.
• General metal workshop projects.
• Machinery and equipment repairs.
• Welding suitable steel sections with compatible electrodes.
