What is the reason that argon arc welding machine doesn't strike fire?
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.
Argon arc welding machine does not strike a spark, the electric switch is not connected, or there is a potential to stick together.Let's do the following:1, wire or handle line is connected and the ground wire and the handle line is intact without virtual connection;2, the earth and the workpiece is virtual;3, handle the workpiece on ignition distance is appropriate;4, turn off the gas to see if there is a squeaking sound or electric column (and lightning almost), there is no high frequency arc ignition, and have to open gas try
The electrical switch is not connected, or there is a potential inside it.
