HFT welcomes new weld purge monitor

Published by

Weld purging is the act of removing oxygen from the vicinity of a weld before, during, and after welding metals. Without weld purging, a weld would be left oxidised and discoloured, which entail loss of corrosion resistance and metallurgical imperfections. In order to accurately read the residual oxygen level inside a tube, pipe, welding chamber or enclosure during the act of purging, Huntingdon Fusion Techniques (HFT®) has designed Weld Purge Monitors to suit all applications and budgets.

HFT welcomes new weld purge monitor

In May, the company welcomed its PurgEye® Desk, which can be used with welding chambers and enclosures, as well as orbital welding machines and other automatic welding systems. The PurgEye Desk replaces the old PurgEye 500, but has new features

The PurgEye Desk has automatic fault finding diagnostics, that can detect and report a number of possible faults. It also features an OLED (organic light emitting diode) display giving brighter, sharper readings at longer distances. This rugged, high frequency proof instrument measures oxygen levels from 1000 ppm down to 1 ppm (accurate to 10 ppm).

The tool has a fast response, long-life sensor with little maintenance requirement. The monitor comes complete with an integral pump to deliver the exhausting purge gas to the measuring sensor on a consistent basis to allow precision control of the welding systems.

Another addition is the company’s PurgeNetTM for the inline connection of several accessories that allows the weld purge monitor to control welding systems based upon oxygen level. PurgeNet controls welding power sources, to switch them on and off according to oxygen levels. The tool can be used with the integrated PurgeLogTM software to transfer weld purge data for quality control of welds.
