Quick question

[Mr Toasty]

Hey guys as the title suggests hopefully it's a quick question, I use pub co2 to weld (just changed from hobby co2) and ive been told that i maight face a freezing up issue in the redulator, and if it does i should invest in a regulator heater? if that's what you call it, if so how does it work and were do i buy one from if i need one?

Cheers for reading Sam

 

[Wozzaaah]

A lot of members use CO2 but I don't recall many issues with regulators freezing.
Some cylinders have dip tubes which draw off liquid CO2 rather than gas, that would cause allsorts of problems but I don't think normal pub cylinders have them.
I could be wrong though (and often am ).

For diy welding you wont have a problem with freezing, unless the flow rate is way too high,
Reg heaters were more commonly found on manifolded gas systems used in industry,
