Hi guys. Can't find any information on this regulator other than the wika gauges. no markings on the metalwork. These were on my co2 bottle when I bought my mighty-mig 100. Bottles were suregas co2 (50bar@15c) My new bottle is an argon mix. 200bar. 10l. Regulator gauge tops at 160 on the dial... Will it work? (do they hanndle more but only read up till 160?) Or is it dangerous? Suggestions please.
