Gas Flow Tester

Every professional welder will have a Gas Flow Tester handy to ensure the correct quantity of gas is surrounding the weld. 
Designed to fit over the nozzle and measure the flow of gas in liters per minute, this devise will not only ensure you have strong welds but it could you save a considerable amount of gas.
Many welders use more gas than necessary 'just to be sure' whereas a gas flow tester will take the guess work out of the equation and pay for itself in no time....!
