MasterWeld® MWF-80D Submerged Arc Welding Flux Oven - 380V

MasterWeld® MWF-80D Submerged Arc Welding Flux Oven – 80kg, 380V, 370°C

British-Made Industrial SAW Flux Drying & Baking Oven | 80kg Capacity | Single-Tank Design | Digital Temperature Control up to 370°C | 380V AC

The MasterWeld® MWF-80D Submerged Arc Welding Flux Oven is a British-manufactured industrial welding flux drying and baking oven, combining an 80kg flux capacity with digital temperature control up to 370°C.

Designed for professional Submerged Arc Welding (SAW) applications, the MWF-80D provides a dedicated heating solution for the controlled drying, baking and conditioning of granular welding flux used in industrial fabrication and manufacturing environments.

As the smallest model in the MasterWeld® submerged arc welding flux oven range, the MWF-80D is particularly suitable for welding workshops and industrial facilities requiring a dedicated flux conditioning oven without the larger capacity of the 200kg or 400kg models.

The oven features a single-tank configuration, providing a dedicated chamber for heating and conditioning submerged arc welding flux in accordance with the flux manufacturer's recommended procedures.

Its electronic digital temperature controller allows operators to select and monitor the required operating temperature, with a maximum temperature of 370°C.

With a 4kW heating output, the MWF-80D provides a controlled heating solution for industrial welding flux drying and baking applications.

Calibration is included as standard, supporting professional welding operations where documented temperature verification is important.

The MWF-80D operates on a 380V AC electrical supply and is designed for installation in industrial facilities with a compatible electrical system.

Manufactured in Britain, the MasterWeld® MWF-80D forms part of our comprehensive range of professional welding consumable drying, baking and conditioning equipment.

Technical Specifications

Single-Tank Flux Drying & Baking Configuration

The MasterWeld® MWF-80D features a single-tank design, providing a dedicated chamber for the controlled heating of submerged arc welding flux.

This configuration is suitable for fabrication workshops and industrial welding operations requiring a dedicated flux drying and baking unit for smaller quantities of granular welding flux.

With its 80kg capacity, the MWF-80D provides an alternative to larger flux ovens where a smaller dedicated conditioning unit is more appropriate for the quantity of flux being handled.

Why Is Submerged Arc Welding Flux Drying Important?

In submerged arc welding, granular flux plays an important role in protecting the welding process and influencing the characteristics of the finished weld.

Depending on the type of flux, exposure to atmospheric moisture during storage or handling may affect its condition and contribute to welding quality problems.

Where recommended by the flux manufacturer, controlled drying or re-baking can help restore welding flux to the required condition before use.

The MWF-80D provides a dedicated heating environment for carrying out these procedures in accordance with the appropriate flux manufacturer's recommendations.

Correct flux handling and conditioning can be particularly important in industrial welding applications where welding procedures specify strict consumable storage and moisture control requirements.

Digital Temperature Control up to 370°C

The MWF-80D incorporates a digital temperature controller, allowing operators to select and monitor the required temperature for flux drying and baking.

With an operating temperature range from ambient up to 370°C, the oven can accommodate a variety of flux conditioning procedures, subject to the flux manufacturer's specified temperatures and heating cycles.

The digital controller provides convenient temperature adjustment for professional welding operations where controlled flux conditioning is required.

Electrical Supply Requirements

The MasterWeld® MWF-80D is designed for operation on a 380V AC electrical supply and has a 4kW power rating.

Before installation, customers should ensure that a compatible electrical supply and suitably rated connection are available. Electrical installation should be carried out in accordance with the manufacturer's requirements and applicable electrical regulations.

Typical Applications

• Submerged Arc Welding (SAW) operations
• Industrial welding flux drying and re-baking
• Heavy engineering and fabrication workshops
• Structural steel fabrication
• Pressure vessel and boiler manufacturing
• Pipe and tubular fabrication
• Shipbuilding and offshore fabrication
• Automated submerged arc welding production
• Welding operations requiring controlled flux conditioning procedures

Why Choose the MasterWeld® MWF-80D?

The MWF-80D combines an 80kg flux capacity with digital temperature control up to 370°C, providing a dedicated solution for industrial submerged arc welding flux drying and baking.

Its single-tank configuration makes it particularly suitable for welding operations requiring a smaller-capacity flux oven rather than one of the larger models in the MasterWeld® range.

The 4kW heating output provides heating capacity for professional flux conditioning, while calibration included as standard supports industrial welding environments where documented temperature verification is important.

For operations requiring greater capacity, the MasterWeld® MWF-200D offers a 200kg single-tank alternative, while the MWF-400DT and MWF-400DD provide 400kg dual-tank configurations.
