What is the cause of the no ignition in the DC argon arc welding machine?
Check the control switch and the circuit is short, if not, then look inside a gap is too large surface is clean. No problem, according to the line has been checked. Some welding machines are set up without air flow and arc free. If the arc striking device is striking the arc, check the gun belt.
As you say, the machine should be all right! Here's a way. You can try: the tungsten electrode is close to the weldment, and the wire is rapidly crossed to make the weldment short circuited with the tungsten electrode in a very short time, which can well ignite the arc!! Have a try!
Not only a gas argon arc welding, argon arc welding and gas protection, before use to check whether the line of gas pipeline, is not fully open, the welder is not FM correctly, if no problem, that is the machine fault, I hope to help you
