In the electro fusion process a heating wire permanently molded into the fitting gets heated by current at a low voltage. The surrounding material around the wire gets melted and expands due to the warming. The melt starts closing the gap between pipe and fitting, leading to a heat transition to the pipe which also gets heated and melts in the welding zone. The pipe material also expands.

The increasing material expansion between pipe and fitting, which is hindered by the cold zones outside the welding zone, leads to a build up a welding pressure between pipe and fitting and a homogeneous welding connection emerges.

Operating Temperature:

  • 14°F (-10°C) to 113°F (45°C)

Input Voltage and Frequency:

  • 100-130 VAC / 200-250 VAC @ 50Hz - 60Hz
Quality housing & components

Encased in a rugged housing and fitted with top-end components, these machines can be used on building sites and in harsh conditions without any problems.

Minimal training required

An intuitive interface enables operators to approach these machines with ease and start controlling the fusion welding process immediately.

Excellent data storage

The internal memory in these machines can store thousands of operational records, allowing for full traceability and rapid job retrieval.

Configurable workflow

As no two welding jobs are the same, the data input settings can be configured according to the workflow for exceptional reliability in the field.

MSA 125 Electrofusion Unit

A robust and ergonomic package that fits in a portable case, the MSA 125 requires no specialist training to use, enabling you to get the fusion process started immediately. It has ample storage for data protocols and a USB port for downloading reports.

MSA 2.0 / 2.1 / 2 MULTI / 2 CF Electrofusion Unit

Robust, lightweight and practical, the MSA 2 series features a barcode scanner, a cooling system for multiple jointing operations and ample internal memory for storing records. An intuitive interface gives the operator a clear overview at all times.

MSA 315/330/340 Electrofusion Units

Simple to operate and featuring a robust aluminum housing, the MSA 315, 330 and 340 electrofusion units control the entire welding process taking into account energy output compensation. These units also have sufficient internal memory to store up to 1,000 jointing records.

MSA 4.0 Electrofusion Unit

The MSA 4.0 is a lightweight electrofusion unit that offers full traceability while documenting the welding process from start to finish. This series comes with built-in GPS and an optional wireless scanner, making it simple to forward data to other locations.
