How to adjust the parameters of inverter DC argon arc welding machine?

Parameter adjustment of inverter DC argon arc welding machine depends on the specifications and models of different machines.

For example, tig-200 reverse DC argon arc welding machine, when debugging, can adjust the change of current from the current, generally the minimum value is 20 amperes.

Then it can be adjusted to the maximum value of 160a, and the trial operation time is 10 minute. If the machine is within this range, overheating and overvoltage will not occur. It shows that the load rate of the machine is ok.

Extended data;

principle of operation

The arc initiation of argon arc welding adopts high voltage breakdown. First, high frequency and high voltage are applied between the electrode needle (tungsten needle) and the workpiece, and argon gas is broken down to make it conductive, and then continuous current is introduced to ensure arc stability.

The working principle of argon arc welding machine in main circuit, auxiliary power supply, driving circuit and protection circuit is the same as that of manual arc welding machine. I won't describe it here, but mainly introduce the unique control function and arc initiation circuit function of argon arc welding machine.

Homogeneous difference

Argon arc welding machine and hand arc welding machine are similar in main circuit, auxiliary power supply, driving circuit and protection circuit. But it adds several controls on the basis of the latter:

1, manual switch control;

2. High frequency and high voltage control;

3. Boost arc control. In addition, in the output loop, the argon arc welding machine adopts the negative electrode output mode, and the output negative electrode is connected to the electrode needle and the positive electrode is connected to the workpiece.
