I do a little bit of welding now and then, just using the disposable bottles from machine mart. The regulator I've got doesn't have a gauge, which is something I really miss. Does anyone know of a regulator that fits the disposable bottles and has a gauge? My google-fu is weak today, can't find one.
I don't think they exist for the disposable bottle regulators. The bottles are quite hit and miss with pressure and only fresh bottles tend to have a good pressure that soon disappears with use.
If you are using a few disposable bottles then think about using Hobby or Adams gas where you but a deposit on the bottle then just pay for the refills. The more consistent pressure and more control from the regulator and flow meter improved my welds no end. I use a Clarke 135TE and now use Argon/CO2 mix as most of my welding is less than 3mm thick
Spoke too soon, they do exist.
I know BOC are generally expensive, but they do a small single purchase* bottle which takes standard gauges. It works out cheaper and more reliable than the disposable ones.
* you don't hire the bottle, just pay a one off deposit.

+1 to this. I've got back into doing welding recently and its a good middle ground between disposables and big bottle rental. Worth looking into, especially if you are planning to buy a new regulator anyway
Hobby Gas or Adams gas is the way to go.
In East Anglia the motor shop 'Wilco' offer replacement bottles, providing you take in an empty.
Personally never messed about with disposable bottles.
Thanks all. I don't do much welding, a disposable bottle lasts me at least 6 months, and I like how it's small enough to clip onto the welder and slide under the bench for storage. If I did more, I'd definitely switch to a proper bottle from one of the various suppliers.
