Air Force reports results @ 7 PPM
Low Oxygen Welding Environment
Simple and effective
Everything as before, Plus
Heard back from the Air Force recently. They report 7 parts per million O2. This is great because their Argon gas contains 5 PPM. Effectively 2 PPM when the gas O2 is counted. Your results may vary, but, if purged properly, with science-grade gas, expect under 10 PPM.
Great for aircraft parts. Titanium welding and another welding that requires low oxygen atmospheres. We like to say that we keep planes in the air with parts that don't break. The photos are for a delivery to Robins AFB near Macon GA.
We make sure you are set up with a personal visit to make sure that everything is working correctly and that your welders know how to use the machine.
The torch is included. Everything is hard fastened to prevent leaks.
