What is formal installation in welding equipment? What is reverse loading?

In the welding process, the two poles of the arc welding machine are respectively connected with the covered electrode and the weldment to form a complete welding circuit. For DC electric welding machine, one is extremely positive and the other is extremely negative. When the weldment is connected to the positive pole, and the electrode base (covered electrode) is connected to the negative pole, it is called the positive connection method (referred to as positive connection for short); otherwise, it is called the reverse connection method (referred to as reverse connection for short). For AC welding machine, because the polarity of the power supply is alternating, there is no problem of forward and reverse connection.

At present, there are many kinds of laser welding machines on the market. Different types of products need different welding machines, and different power wattage of the machine will also cause different prices. It mainly depends on the products you weld, and then determines the type of machine you use.
