The main reason for my visit was to find the leak that was causing the customer to go through a bottle of argon in a week when other operators are getting two weeks out of a bottle.
However upon checking the reg as the gas line from reg, through the machine and out to the torch it became obvious there was no leak.
A quick test of the gas flow showed the bobbin on the flowmeter to be hitting the top of the sight guage and if I opened the tap on the flow meter the flow increased significantly. They are on 4-6mm ally and using standard ceramics so somewhere between 10-12 lpm at the reg would do. It turned out they were using a tip flow meter to set 12 lpm at the torch. Due to drag from the pipes/gas valve etc 12 lpm at the torch equates to about 18-20 lpm at the reg. mystery solved, gas runs out twice as fast when you use it twice as fast.
