The Thermamax Vulcan 1200A Dual is Unique Welding’s latest heavy-duty, locally manufactured engine-driven welder, built specifically to meet the demands of African construction sites, remote operations, and mines where grid power is unreliable or unavailable.

This all-in-one mobile unit delivers a massive 1 200 A of welding current, driven by two high-performance 600 A multi-process inverters powered by a turbocharged Perkins diesel engine and generator system.

Built for Demanding Conditions

The Vulcan 1200A Dual offers unmatched flexibility and endurance:

• Dual inverter system 

Two 600 A inverters can run independently and simultaneously, powering up to three welding arcs at once without interference.

• Multi-process capable

Supports MIG, Stick/MMA, Scratch TIG, and arc-air gouging with easy process selection and a single dial to adjust welding parameters.

• Integrated compressor 

A built-in high-pressure piston compressor (5.5 kVa motor) enables arc-air gouging while welding operations continue, maximising on-site productivity.

• Auxiliary outputs 

Includes two 380 V three-phase and two 220 V single-phase outputs to power additional tools or welders.

• Fuel efficient 

Runs for about 12 hours on a 100 ℓ diesel tank, depending on load.

The welder is operator-friendly, safe and designed for simplicity and safety.

• User interface 

Intuitive front panel with one switch and one power setting per inverter.

• Digital control 

Provides stable, programmable CV output, compatible with standard wire feeders.

• Mining-compliant safety features 

Includes lock-out electrical isolation for maintenance and a Voltage Reducing Device to minimise risk when the arc is not active.

Custom-Built and Backed Locally

The Vulcan 1200A Dual is locally produced in South Africa, allowing for customisation to suit specific operational needs. Orders can typically be fulfilled within six weeks of finalising specifications. Each unit is backed by a two-year warranty and supported by Unique Welding’s nationwide footprint and technical expertise.

As one of the country’s leading gas and welding solution providers, Unique Welding continues to raise the bar with innovative, cost-saving and practical solutions like the Vulcan 1200A Dual, delivering real-world performance where it matters most.
