Although I'm ok with arc-welding, I'm brand new to this MIG malarky ...
Being a bit tight in the wallet department, a few weeks back I picked up a old Sealey 120XT which I'm hoping will be good enough to cut me teeth on.
First job was to replace the soda-syphon bottle with one from a closed-down pub, which came complete with a busted regulator. Although I wouldn't dream of playing with an oxygen regulator, I reckon CO2 is safe enough, so I took the thing to pieces. The fault was eventually traced to an over-pressure relief valve, the rubber seating washer of which had dissolved into goo (!).
Can anyone advise what kind of static pressure (i.e. at zero flow) the regulator should be set to ? I'll then set the pressure relief valve to that pressure plus 25%.
For now I've set the reg at 15 psi and the welds look kinda reasonable for a beginner.
I have an ex-oxygen flow meter (ball-bearing in a vertical tube type) which I plan on fitting to monitor flow rate - can anyone advise an appropriate rate (?) - the meter itself is calibrated from 1 to 12 litres/min.
Any help/advice appreciated.
Thanks
Colin
