The gas test button opens the gas valve without activating the wire feed or power source. Gas
flows for 20 seconds by default. The display shows the remaining gas flow time. The default
time of gas flow can be adjusted via the right-hand potentiometer within a range of 0 to 60
seconds. The new time setting is recorded in the memory. The gas flow can be discontinued
by pressing the ON/OFF button or the start switch of the gun.

The weld data function is activated by pressing buttons 5 and 7 simultaneously. The weld
data function returns the welding current and voltage values to the displays that were in use

Operation returns to normal approx. 3 seconds after release of the button or if the ON/OFF
