Purge monitor solves welding problems

Condaire Inc. (St Louis, Missouri, USA), had problems with the purging of critical stainless steel pipework, with welds oxidising in spite of following correct weld procedures. So that the welding operatives could try to evaluate the difficulty, Huntingdon Fusion Techniques Ltd loaned a MKIV Welding Purge Monitor. In a very short time, Mr Phil Jones or Condaire, called the distributor and said that “The Argweld Purge Monitor did the trick and showed us exactly where the problem was”. Condaire purchased the monitor for future work. The Argweld Purge Monitor is a hand-held, battery-powered, portable. It can be used to measure the oxygen level in the welding of stainless steel pipes and pipe work fabrications as well as for welds being made in welding enclosures or chambers. It will measure oxygen levels down to 500 parts per million by connecting it to the exhaust flow of the purge gas or by taking samples of the gas quality in the purge space from time to time. Savings achieved by using this monitor will pay for it in only a few welds.
