Does anyone know if a standard flow regulator be connected inline with the pressure regulator that comes with the Clarke 160TM as standard, or would I be better going for a new integrated regulator/flow meter?
Your regulator is likely to be different to the UK version Shenion.
The one's supplied with the 160TM have just a cylinder contents gauge fitted & there is no provision for a flowmeter...the only removable "restrictor" is actually a pressure relief valve for safety & should NOT be removed.
The easiest way to set the gas flow, without buying a 2 gauge gas regulator, is with a 'Gun Gas Flow Tester'. These simply go on the end of the welding torch & you can set the gas flow when you press the torch trigger...bit like a Flowmeter but you remove them when the pressure is set.
