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.

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.

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.

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.

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.

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.

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?

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.

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.
