Argon arc welding machine has high frequency spark, no arc, what are the reasons? Repair steps: argon arc welding machine has high frequency sparks, no arc, check whether the gun has sufficient amount of argon to come out, and then see if the cable is broken!I have encountered such a situation when the broken welding torch cable, welding machine apart was measured with a multimeter in many places did not find the problem, then the part of the high pressure spark open press with a multimeter to check the output terminal of the switch + fast welding (workpiece) and - (argon arc welding) end are the normal voltage, (at that time not see) arc welding torch cable can be! The torch cable to replace fixed ~!
Brother, you are the same as me! Every step has been checked: no problem! Later also changed the welding tape. The trouble has been eliminated!
The torch cable breaking is not completely broken, the high-frequency pathway is a high voltage low current, but the welding current is larger than the high-frequency current and the arc voltage is much lower when the welding voltage, welding torch cable problems when welding arc voltage is too low, so not arc.
The first is to look at the adjustment of the problem, there is no, and some arc current is small will have an impact, second is slow rise time adjustment is not too long, wit welding machine has one is, you adjust the time is long, just can't afford. This is the most basic you should be familiar with your machine in check the welding line, if not, can only find vendors or manufacturers, generally a lot of things are a single phone warranty convenient and easy, as in other manufacturers to what they can learn to really, if the warranty expired, only power in familiar situations after the examination, if not find professionals.
First make sure there are no high-voltage ignition sound, then check the contact switch and the contact line not is good, then check the high-voltage circuit, see high voltage capacitor capacity, there is a high frequency inductors have a great relationship, have a lot of argon arc welding machine is the case, the largest Wuxi welder.If there is a high frequency, change a gas or electricity connector or a quick joint.Try to transfer the discharge nozzle a little further. The tungsten electrode 0.5CM switch has no high frequency arcing when it is switched on. If there is no arc ignition circuit, there is a fault.Switch line may have broken place, you can unplug the switch, and even with a flat screwdriver, see, OK, and there is listen to there is no electromagnetic valve pull sound.
