The surging power of the pneumatic stainless steel spot welder certainly comes from its core component, the AC transformer. The quality of the transformer determines the output effects of the spot welder, butt welder, and seam welder.

Labor-saving stainless steel spot welding machines are generally pneumatic spot welders. They are popular spot welding machines used in most mechanical equipment, automobiles, motors, sheet metal, medical equipment, hardware and electrical appliances and other industries in China. Their power ranges from small to large, and their applicable scope is as shown in the table:

Compared with the lever pedal spot welder, the pneumatic stainless steel spot welder has a much more complex process and is also the largest-selling model among resistance welders. It can not only weld stainless steel, galvanized plate, mild steel, round wire, filter screen, low alloy, but also can weld copper, aluminum, etc. by replacing the electrode head.

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

Spot welding machines are divided into foot-operated spot welding machines, pneumatic spot welding machines, and medium-frequency spot welding machines, which are subcategories of resistance welding machines. Pneumatic spot welding machines are generally power frequency AC spot welding machines that use cylinder compressed air to compress the workpiece to save labor.

This BDN handheld spot welder is specially designed by Xinxing for welding thin steel strips and aluminum strips. It has a beautiful, high-end, convenient and practical table top style and a reasonable price. It is very popular in more than 100 countries and regions including China, Russia, and Southeast Asia.
