If you want to know about resistance welding machine welding knowledge, welding methods and welding cases, you can find them here

Today, we used a 160KVA DTN stainless steel spot welder and a medium frequency spot welder of the same power to test weld the truck hinge shaft respectively to compare the post-weld effects so that customers can choose a more suitable spot welder. After all, the price difference between the two models is a bit big.

Each manufacturer’s spot welding machine is slightly different in structure, and the operating precautions of the welding machine are also different. The spot welding machine here is a DTN stainless steel spot welding machine, which is one of the Xinxing welding machine pneumatic spot welding machines. The precautions before operation are as follows, please read carefully.

Last time when we were installing a flash butt welding machine for a customer, an operator asked how to use the counting and pause functions. At that time, we were stunned. Such a simple question came up blank. The settings above are the same as those on the DTN stainless steel spot welder controller.

The prices of pneumatic spot welders on the Internet vary widely. As a buyer, you need to click on them one by one to take a closer look at the prices. Many of the low prices are deposits, some are introductory prices (a strategy to divert traffic), some have very small power and the workpieces welded are very thin.

The power of the DTN stainless steel spot welding machine is determined based on the thickness of most workpieces on the market. As an accessory, the water-cooled electrode is selected based on the power. The diameter of the electrode rod and the size of the electrode head are selected based on the power. So what kind of power is equipped with what specifications of electrodes?

Why do you say that? Pneumatic spot welding machine is first of all an industrial spot welding machine. It is fast, precise in control, labor-saving and time-saving. The voltage is 380V. It is cost-effective to weld continuously on large-volume workpiece production lines.

Whether it is a DTN stainless steel spot welder or a medium frequency spot welder, high heat will accumulate inside during welding. The rising temperature will easily soften and wear the copper of the welding head and transformer. In severe cases, it will be transmitted to electrical appliances, thereby shortening the service life.

Pneumatic spot welding machines and foot-operated spot welding machines are very different in terms of appearance, configuration, structure, function, performance, maintenance, etc., and the prices are naturally different. Let’s compare them bit by bit.

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.
