Butt welding machine-spot welding machine industry trends

Stainless steel spot welding machines and projection welding machines are sometimes very similar, with only 1/100 difference. That is because projection welding is a deformation of spot welding. In many cases, only the electrode welding head is different. If it is replaced with a tapered electrode, it is called a spot welding machine, and if it is replaced with a flat welding head, it can be called a projection welding machine.

Some time ago, a customer in this city went straight to Xinxing Welding Machine and wanted a stainless steel spot welder that can weld both folds at once. After constant communication and understanding, the two parties signed a supply and sales contract.

Recently, a Changzhou customer brought a hoop made of 3 layers of stainless steel to the Xinxing Welding Machine Factory to test the pneumatic stainless steel spot welding machine on site. After continuous communication, welding and peeling tests, the customer was very satisfied, and finally the two parties signed a letter of intent for cooperation.

Pneumatic stainless steel spot welding machines and butt welding machines do look similar, just like today’s mobile phones. There is not much difference in style. It is necessary to carefully disassemble its components to screen out its differences, at least to look at its core components, such as controllers, transformers, etc.

A few days ago, a customer came to the Xinxing welding machine site with a wire hook. He wanted to find a pneumatic stainless steel spot welder with a reasonable price for trial welding. After a personal trial welding, the positioning was accurate, easy to use, and the welding was firm. It met the requirements of foreign users. The customer liked it very much and decided on the spot.

When it comes to the price of a stainless steel spot welding machine, I have to say that it depends on the thickness of your workpiece. If two workpieces are stacked together and are less than 2mm, the price is 50-1.3W yuan. Those with strong hands-on skills can make one by using a used microwave oven transformer and adding some small accessories for 50 yuan.

Sparks splashing when the stainless steel spot welder is welding indicates that the welder is an old-fashioned spot welding butt welding machine. Its current is straight up and down, just like a faucet. You can open as much as you want and the output will go out without fine control. In addition, resistance spot welding machines are characterized by high current and low voltage, so sparks are prone to occur.

Good quality pneumatic spot welding machines on the market are generally resistance AC spot welding machines, and the controllers used have three modes: constant voltage, constant heat, and constant current. The factory default is constant voltage mode, but in actual operation, constant current mode is more needed, so it is crucial to master the setting of constant current mode.

The pneumatic spot welding machine here refers to a power frequency AC spot welding machine, a type of resistance welding machine. Its controller generally has three modes: constant voltage, constant heat, and constant current. To adjust the constant heat mode, follow the steps below: 1. Press the power switch at the bottom of the controller
