CO2 Heater

[AndyStobbs]

I remember seeing a heated reg for a pub bottle on ebay years ago. It claimed to improve the weld quality in a major way.
Something just re-ignited the memory, and I'm wondering if there is much truth in the claim?

All they do it stop the regs/lines freezing with heavy draw-off rates.

Well it will stop the neck freezing up and reducing your flow of co2 so it won't produce better welds it will just keep them consistent I'd think, can't see any other reason for heating it up

Ah, so hardly applicable to the average person. Thanks Paul

Think my little snap on 2135 runs up against the limits of duty cycle long before the neck ices up haha.

Never used co2 always argosheild

I only ever used argosheild at college. I weld everything with co2. Mainly car stuff; body work, exhausts etc.
Do some other larger pieces too, upto the limits of the welder really.

CO2 heaters were more common when CO2 was not pure and had water vapor in it. The heater prevented the water from condensing.

Now CO2 is much more pure.

Unless you are running several welders off a reg, you should not see the reg freeze.

Heaters were popular a few years ago when CO2 was the main welding gas, last time I used them was building a welding machine for India where CO2 is still popular.
