Weld purge
monitoring
THE portable PurgEye® 200 weld purge monitor is designed
to meet the needs of higher welding specifications requiring
oxygen levels down to as low as ten parts per million
(ppm).
The handheld PurgEye 200 from Huntingdon Fusion
Techniques (HFT) is totally waterproof and dustproof. It
has warning icons on the large screen to show low battery
and low sensor conditions, and also displays oxygen
readings in percentage or in ppm very accurately down to
10 ppm.
Luke Keane, distributor support for HFT, said, “Weld
purge monitors are an essential instrument to help
obtain non-oxidised, zero-colour welds by monitoring the
oxygen level when welding metals such as titanium and
zirconium where high quality and high strength welds are
required.
“the PurgEye 200 also finds a place with those making
important zero-colour joints in stainless, duplex and chrome
moly where a metallurgically pristine weld is produced with
the help of high quality purging.”
the PurgEye 200 contains an internal electro-mechanical
pump for automatically drawing samples of purge gas over
the sensor before discharging it to the atmosphere. The
lifetime sensor eliminates the need for changing cells every
year or so, as is the case with wet cell instruments.
Alarm signals can be given by the PurgEye 200 to show
when the oxygen level is within or outside the required ppm
range.
HFT has a range of PurgEye weld purge monitors to
measure oxygen levels from atmospheric content (20.94%)
down to 1 ppm (accurate to 10 ppm), at which point no
discolouration in welds of any kind should occur. By striving
for zero-colour welds, companies can eliminate the post-
weld cleaning costs of oxidised welds.
