Argon arc welding machine why arc small, current is small, how can I solve?

Answer:

You use or old-fashioned power rectifier argon arc welding bar, small current is auxiliary superimposed power supply, the main circuit of the electric output, which is not specific, and suddenly said it is not clear.
The general welding process are taken in low voltage, high current process parameters for welding, argon arc welding machine has two kinds of welding methods, one is set to normal welding, a special set for the four step, but as said above two kinds of welding methods in local parameters of arc greater than the normal welding parameters, this is because the workpiece started when welding workpiece is cold heat output slightly, but this also prone to crack, so usually at the start of an arc increase an arc plate to prevent the generation of cracks in weld normal.
