There are several argon arc welding machines in our factory. There is a problem with it. To put it plainly, sometimes it can lead to arc. Sometimes it is very close and can not arc. Abnormal welding. Come on, master!
The welding machine needs cleaning. There are two pieces of copper in it. The electric shock can be cleaned or a little closer, and the welding machine itself may be cold
First, it may be too high or too weak or high frequency! Second, tungsten quality is poor, third welding torch copper wire open!
1: high frequency plate aging, high frequency ignition ability is reduced. Continuous welding does not require repeated arc striking, and arcing is difficult when arc welding is broken. The problem can only be solved by replacing the new high frequency board.2: high frequency plate put point electrode gap is not, or burning serious, with fine sandpaper or gauze lightly grinding discharge electrode, re installed. Severe burning and replacement of new electrode when necessary.3: continuous high current welding, argon flow is smaller. Tungsten oxide oxidation. The oxidized tungsten electrode affects the electrical conductivity, and the arc breaking spot welding also affects the arc initiation performance. Continuous arc welding does not require repeated arcing, and no arcing phenomenon can occur. Increase argon flow according to welding process.
