Why argon arc welding only fires without current?
There may be a high pressure package will be bad, but generally not high voltage package failure. Argon arc welding machine is not a simple welder with argon gas protection. On the one hand, the no-load voltage is low; on the other hand, it is possible to reduce the capacitive capacity of the high voltage arc ignition circuit.Argon arc welding machine slow ignition, this normal. After pressing the switch of the welding torch, the electromagnetic valve in the welder is started.Argon arc welding machine, are ahead of its protection role of gas welding. Argon is used to blow air around the weld line of the workpiece to be welded so as to avoid penetration of the weld through the air. The arc then starts and enters the normal welding process.Each brand of each model of argon arc welding machine, the delay time is different, some welding machine can be adjusted.Argon arc welding, that is, tungsten inert gas arc welding, refers to the use of industrial tungsten or activated tungsten as non melting electrode, inert gas (argon) as the protection of welding methods, referred to as TIG.
There is no argon or ground wire is not connected
From what you say, in fact, is in the high frequency oscillation of argon arc welding machine transmitter, reach hundreds of thousands of volts in instantaneous voltage, forced air breakdown (when used to Caution!) so as to achieve the positive to negative contact! But now pulses are better than high frequency ones!
