Bargin for price but be aware that you will get more pressure when co2 first comes on until it equalises pressure build up. also it may give end of tank dump as co2 runs out
Westcol and sif regs are much better and all single stage regs are prone to end of tank dump
2 stage co2/argon regs rarely come up for sale unlike oxygen which come up quite often
All 2 stage regs have a stainless diaphram in the first stage and a neoprene diaphram in the second stage and are co2 safe but the fitting is male and an adapter cost around £20 and regs can be bought new for around £45-65 from welding suppliers
Does this mean you can use pretty much any regulator for co2 aslong as we use adapters or change the fittings ? I was lead to believe from the research I did that you could only use co2 regs for co2 as the co2 will degrade the diaphragm ?
