2/0 AWG Welding Cable Features

Welding cables are usually made of single-strand filaments twisted and wrapped with polyvinyl chloride or rubber insulation sheath. They are special cables used for secondary side wiring of electric welding machines and connecting welding clamps and electric welding machines. If the insulation sheath of the cable is PVC, it should be thermoset to better resist welding spatter. The sheath material is made of natural rubber or neoprene mixture, and the neoprene mixture sheath has heat resistance, oil resistance and non-flammability, so it can be applied to different occasions. Welding cables should be flexible and durable. Whether it is automatic welding or manual welding, the application requires the cables to be able to withstand repeated movements on rough surfaces. Commonly used welding cables have a cross-sectional area between 10mm² and 240mm².

Models of 2/0 AWG Welding Cable

YH welding cable: the insulation and sheath are combined into one layer, the thickness is thicker, more than 1.8mm, and the material is natural rubber mixture,

YHF welding cable: There are two covering layers, one is neoprene compound, the other is rubber compound as insulation, and neoprene compound as sheath.

Features of 2/0 AWG Welding Cable

1.YH Welding Cable work under the condition of low voltage (maximum voltage 200V) and high current, which requires certain resistance.

2.The long-term allowable working temperature of the welding cable does not exceed 65°C.

3.Welding cables will be frequently moved, twisted and released, requiring softness and good bending performance.

4.It is easy to withstand friction and scratches by sharp steel components during use, so the insulation layer of the cable is required to have good mechanical properties such as tear resistance and wear resistance.

5.The use of complex environmental conditions, such as sunlight, boiling water, contact with muddy water, engine oil, acid-base liquid, etc., requires a certain degree of weather resistance, oil resistance, and solvent resistance.

6.Sometimes hot welded parts are encountered, and good heat deformation resistance is required.

7.The welding cable will often move during use, so it is required to have a small outer diameter and light weight. Due to the low requirements on the electrical performance of this kind of cable, and the complex environmental conditions of use, it is not appropriate to meet various complex environmental factors in structure. Therefore, attention should be paid to improving the conditions of use during use to prevent damage to the cable caused by external factors.

2/0 AWG Welding Cable data and selection

1.2/0 AWG Welding Cable Ampacity

It refers to the amount of current that a cable line passes when transmitting electric energy. Under thermal stability conditions, the cable current carrying capacity when the cable conductor reaches the long-term allowable working temperature is called the long-term allowable current carrying capacity of the cable. Welding cable ampacity is different from other cables, it requires higher ampacity.

2.2/0 AWG Welding Cable Selection

When choosing the welding cable correctly, factors such as the output power of the welding machine, the duty cycle and the length of the cable should be considered. The rated output of the welding cable determines the maximum current the power supply can draw during operation. The cable must be sized to handle the maximum current.

The welding circuit usually consists of welding power supply, electrodes and cables. The length of the circuit should be determined by calculating the total length of welding cables and other work cables. Due to the greater resistance of longer cables, the ampacity decreases with length. Welding cables consume electric energy. The thinner and longer the cable, the more electric energy it has. It is recommended to use a welding cable with a larger cross-sectional area for long-term welding, which saves the consumption cost during the use of the cable, and is also conducive to Quality maintenance of welding cables.

In addition to choosing the proper cable diameter, it is important to keep your welding cables and working connections in good condition. Any cracks, cuts, wear points, etc. in the welding cable will reduce its current carrying capacity and cause local overheating. In addition, the wear and tear of the cable link of the ground clamp, wiring or joint will also reduce the carrying current and cause local overheating. All worn and damaged parts should be repaired immediately to allow for proper operation and reduce any potential safety hazard.

2/0 AWG Welding Cable Safety Requirements

Welding Cable is an insulated wire connecting the welding machine and welding torch, welding parts, etc., and should meet the following safety requirements:

1.First of all, it should have good electrical conductivity and insulation properties.

2.It needs to be light and soft, can be bent and twisted arbitrarily, and is easy to operate.

3.It should have good mechanical damage resistance, oil resistance, heat resistance and corrosion resistance.

4.Its length should be determined according to the specific use situation, and should not be too long or too short.

5.There must be an appropriate cross-sectional area. The cross-sectional area of the welding cable should be used according to the size of the welding current to ensure that the cable will not overheat and burn the insulation layer.

6.The whole welding cable should be used, and there should be no joints in the middle. If it is necessary to use short wires to connect long cables, there should not be more than two connectors. When connecting long cables, they should be firmly connected with joint connectors, and the connection should be well insulated.

7.It is strictly forbidden to use the metal structure, pipes, tracks or other metals of the factory building to be used as wires.

8.Do not place the welding cable next to the hot weld metal near the arc to avoid burning the insulation layer, and at the same time avoid rolling and abrasion, etc. It is forbidden to contact the welding cable with combustibles such as grease.

9.Copper wire must be used for the connection between the welding cable and the welding machine to avoid fire.

10.The insulation of welding cables should be checked every six months.
