Product Operate Guide   

 

Press the activation button on the touch screen control panel window.

Wait for 5 seconds to allow the pipelines inside the spray gun to circulate. Then click the start button, and the running indicator light will turn on. 

The console will automatically initiate the following procedures:

a. Cooling water ON

b. Powder feeding carrier gas ON

c. Ignition system ON

d. Small flow rate oxygen ON

e. Small flow rate fuel ON

f. After a few seconds' delay

g. Standby flow rate oxygen ON

h. Standby flow rate fuel ON

Press the button to switch to the running state, so that the oxygen and fuel flow rates rise to the set values.

Depending on the type of spraying powder, the flow rates of oxygen and fuel can be precisely adjusted on the console to obtain a slender cylindrical supersonic flame with 5 - 12 Mach nodes.

Click the powder feeding button to start the powder feeding and spraying operation.

Shutdown operations:

a. Click the powder feeding button again to turn off the powder feeding. After waiting for 5 seconds, press the stop running button, and the oxygen and fuel flow rates will gradually decrease in a linear proportion until the spray gun flame is extinguished.

b. For emergency shutdown, directly press the emergency stop (total stop) button. Generally, this shutdown method is not recommended.
