What is the problem of inverter type hand arc welding machine without arcing?
Check the following possible: diode bad, circuit board bad, power supply phase missing, power supply insurance burned, the template is bad.Manual arc welding, referred to as hand arc welding, is a manual welding method that uses the heat produced by the arc to melt and welding electrodes.There are many health hazards in welding operations, which can be divided into two major categories: physical and chemical factors. The former has high temperature electric arc generated ultraviolet, infrared and so on. The latter is the various components of the welding aerosol, solid state has a variety of metals iron, manganese, aluminum, chromium, lead, nickel, radioactive elements, etc., the gas phase of manganese oxide, hydrogen fluoride, nitrogen oxides and other gases such as [1]. High temperature, vibration and noise are not obvious.The dispersion of welding aerosol is very high, and its biological activity is obviously higher than other dust. Welding electrode and welding method are different. The composition of the welding aerosol varies greatly, and the biological activity is also different. The biological activity of [2] is related to the solubility and freshness of the welding fume
