Hi all.
I have a older CIG cutting torch (mixer) which takes "Type 37" tips. I have a selection of these tips, but the numbers on them are not related to anything I know.... E.g. Number 0 is quite large (looks like a number 15 in Type 41 - the common current system). There is als a Nmber 4, a Number 7 and a couple with numbers like 45-12....
I can't find anything about Type 37 tips anywhere on the net....
Anyone have any of those and know what the numbers mean?
Or can I just measure the oxy hole in the middle and compare those with the current types?
