Recently we changed an acetylene tank in the school I’m involved
with. We have 2 tanks and soldering stations set-up. The flame is
very yellow though still with a blue cone when using the new full
The other tank produces a bluish flame. Thinking something was not
working properly with the hose, handle or torch tip ( everything was
purchased new 1 1/2 years ago) I switched the entire set up (
including regulators) between the 2 tanks. The flame was still
yellow on the new tank. I’m a bit mystified.
Any would be helpful.
