Features
Simplified Control Panel: Intuitive interface with clearly marked controls for essential welding parameters, minimising setup time and maximising welding efficiency. Focus on the weld, not complex menus.
High Output Current (400A at 60% Duty Cycle) : Enables welding of thick materials and tackling demanding industrial applications with ease. Provides ample power for consistent, high-quality welds.
Versatile Material Compatibility: Capable of welding a wide range of materials, including mild steel, stainless steel, aluminium (with appropriate wire and gas) , and other alloys, offering flexibility for diverse projects.
Robust and Durable Construction: Built with heavy-duty components and a rugged chassis to withstand the rigors of demanding work environments, ensuring long-lasting performance and reliability.
Energy-Efficient Design: Incorporates advanced inverter technology and optimised power management to minimise energy consumption, reducing operating costs and environmental impact.
Precise Arc Control: Delivers a stable and consistent arc, resulting in smooth, clean welds with minimal spatter and improved weld quality.
Integrated Wire Feed System (or Separate Wire Feeder Option) : Offers precise and consistent wire feeding for optimal welding performance. Separate wire feeder models enhance maneuverability for welding in difficult-to-reach areas.
4-Roll Wire Feed System: Provides superior wire feeding control and minimises wire deformation, especially beneficial for softer wires like aluminium.
Burn-Back Control: Prevents the welding wire from sticking to the workpiece after welding, ensuring a clean finish and reducing downtime.
Gas Pre-Flow and Post-Flow Control: Optimises gas usage and protects the weld pool from oxidation, resulting in higher quality welds and reduced gas consumption.
2T/4T Trigger Control: Offers flexibility for different welding techniques. 2T (2-Touch) for short welds and 4T (4-Touch) for longer welds, reducing operator fatigue.
Overload and Thermal Protection: Built-in safety features that protect the machine from damage due to excessive current or temperature, ensuring long-term reliability and operator safety.
Easy Access for Maintenance: Designed for easy access to internal components for routine maintenance and servicing, minimising downtime.
Optional Intelligent Gas Control (IGC) : Further reduces gas consumption by automatically adjusting gas flow based on welding parameters.
Compatibility with Various Torches and Consumables: Offers flexibility to choose the right torch and consumables for specific welding applications.
Digital Display: Provides clear and accurate display of welding parameters for precise control and monitoring.
Euro Connector for Torch Connection: Standardised connection for easy torch replacement and compatibility.
Suitable for a Wide Range of Wire Diameters: Accommodates various wire sizes to suit different welding applications and material thicknesses.
Meets Relevant Industry Standards: Complies with all applicable safety and performance standards for welding equipment.
