TWA Certifications Limited is a specialised, high quality welder training and support services academy based on Chester West Employment Park.

Owned and operated by Kevin Birmingham since July 2021 TWA Certifications Limited offer a range of training courses and welding activity support services to a wide range of customers.

TWA Certifications Limited were previously using standard welding gas cylinders from an Energas competitor. A demo for Qlixbi was arranged with Energas and the benefits for the training facility could quickly and easily be seen by Kevin Birmingham and his team. The contract for the supply of Qlixbi was signed and TWA Certifications Limited began using Qlixbi brought to them by Energas, in July 2021.

Qlixbi’s unique click on connector has now allowed us to have more time with all of our learners.


“Here at TWA Certifications, Qlixbi has made a real difference in how our training school runs. Gone are the days of all day changing bottles and finding bottle spanners. Qlixbi has reduced the time to a few minutes rather than the 10 minute process we are all used to. As time is always short in any training environment as everyone is wanting your attention, Qlixbi’s unique click on connector has now allowed us to have more time with all of our learners. Not only are we saving time it ensures all bottle changes are easy, quick, safe and no leaks, no wastage. Qlixbi is having a big, positive impact in our environment and would recommend it to any other welding business.”
