What is the general current for welding?

Electric welding machines are generally divided into the following categories according to the current specifications.

160、 180、200、250、3 15、400、500、630、800、 1000、 1250、 1600、2000、2500、3 150

The types of welding machines corresponding to these currents are mainly divided into

ZX7 series manual welding machine, WS7 series argon arc welding machine, WSE series AC /DC square wave argon arc welding machine, NBC series carbon dioxide semi-automatic gas shielded welding machine, MZ7 series automatic submerged arc welding machine, etc. , as well as TIG small argon arc welding machine and LGK series plasma cutting machine.

Introduction of electric welding: Electric welding is the common name of covered electrode electric arc welding. Covered electrode is used to melt metal parts at high temperature, and the welding operation where arc connection is needed. The basic working principle of electric welding is to use 220V voltage or 380V industrial electricity.

Current: scientifically, the amount of electricity passing through any cross section of a conductor in unit time is called current intensity, which is called current for short. Usually expressed by the letter I, its unit is ampere (André-Marie Ampère), 1775- 1836, a French physicist and chemist, who has made outstanding achievements in the research of electromagnetic action and contributed to mathematics and physics. Ampere, the international unit of current, is named after its surname. The symbol "a" also guides the directional motion of charges in the body.
