Huntingdon Fusion Techniques-USA Inc. has released the new MKV version of the Argweld Weld Purge Monitor. The monitor provides welders and quality control personnel with information about the Oxygen content in the vicinity of their weld joints. This allows optimisation of welding conditions, reduces waiting time, and assists in avoiding weld reject. Each monitor comes supplied in a robust carry case, with a stainless steel sampling probe, 2m length of rubber hose, a vacuum sampling hand pump and a carrying strap. This instrument can be used to continuously monitor the oxygen level, even when welding is taking place, by attaching the exhaust tube from the purge system directly to the monitor. In addition, the metal sampling probe with the hand pump can be used to check the purge gas quality at frequent intervals. This instrument can be used when welding titanium, duplex steels and stainless steel and can be used in conjunction with HFT’s range of Argweld Inflatable pipe Purging Systems.
