Tank welding machines are actually transformers with lower external characteristics, which convert 220V and 380V alternating current into low-voltage direct current. Electric welding machines can generally be divided into two types according to the output power source. Therefore, tank welding machines can be divided into many types according to different characteristics.
Here is the content list:
l Tank welding machines are classified according to power characteristics.
l What types of tank welding machines does WINCOO have?
l What are the classifications of tank welding machines based on the market industry?
One type of tank welding machine is AC power and the other is DC power. A DC welding machine can be said to be a high-power rectifier. It is divided into positive and negative poles. When AC power is input, it is transformed by a transformer, and then rectified by the rectifier, and then outputs a power source with reduced external characteristics.
The output terminal will produce huge voltage changes when it is switched on and off the tank welding machines. When the two poles are short-circuited momentarily, the arc is ignited, and the generated arc is used to melt the electrode and welding material, and after cooling, the purpose of combining them is achieved. Welding transformers have their own characteristics. The external characteristic is the sharp drop in voltage after the electrode is ignited.

What are the components of hydraulic storage tank lifting equipment?
What is the role of hydraulic storage tank lifting equipment?
What are the classifications of hydraulic storage tank lifting equipment?
Air filter: Prevent foreign debris from mixing, filter the air, and balance the pressure in the fuel tank and the atmosphere.
Oil level gauge: Used to observe the amount of oil in the tank. When the tow pump is working, the oil level must be above the middle of the oil level.
Thermometer: Displays hydraulic oil temperature.
Quick refill connector: used for filling of hydraulic oil.
Drain valve: It is used to remove dirty oil when the fuel tank is cleaned, and it is usually closed.
Hydraulic storage tank lifting equipment is a special container, in addition to storing hydraulic oil, it also has the function of dissipating heat and depositing grease. Therefore, in addition to cleaning the oil tank, the upper cover of the hydraulic oil tank cannot be opened casually, and an air filter is set on the oil tank to communicate the atmosphere with the air in the oil tank through the filter. Hydraulic oil tank is generally composed of quick refueling joint, air filter, thermometer, oil level gauge, oil suction self-sealing device, box body, drain valve and other main components.
Universal hydraulic storage tank lifting equipment is suitable for various lifting operations with small lifting height. It consists of oil chamber, oil pump, oil storage chamber, piston, crank handle, oil valve and other main parts. When working, as long as the crank handle is moved back and forth, the manual oil pump continuously presses oil into the oil cylinder. Due to the continuous increase of the oil pressure in the oil cylinder, the piston and the weight on the piston are forced to move upward together. Open the oil return valve, and the high-pressure oil in the oil cylinder will flow back to the oil storage chamber, so the weight and the piston will fall together.
The special hydraulic storage tank lifting equipment is a special tensioning machine, which applies tension to the prestressed steel bars when making prestressed concrete members. The dedicated hydraulic storage tank lifting equipment is mostly double-acting. There are two commonly used types: through-heart type and cone-anchor type.
The feed-through jack is suitable for tensioning steel tendons or wire bundles. It is mainly composed of a tensioning cylinder, a top-pressing cylinder, a top-pressing piston and a spring. Its characteristics are: there is a piercing hole along the axis of the stretching machine, and the steel bar (or steel wire) is anchored by the tool at the tail after being penetrated.
