There are two types of fusion welding burns, one is contact burns and one is arc burns. Contact burns is the human body in direct contact with high-voltage electricity, the current through the human body caused by injury, due to the current directly burns the body, will cause the degree of injury is a little heavier, generally deep three degrees of burns. Arc burns are due to high voltage electricity to produce two electrodes, the formation of a kind of bright bridge, the formation of instantaneous high temperature, the general role of the time is shorter, resulting in the degree of burns is also lighter, generally in the deep second degree burns. These two kinds of burns clinical manifestations to scalding, treatment according to the degree of scalding, can be taken to control the inflammation, restore the skin or surgical implantation method of treatment. General welder burns are caused by improper operation, so be sure to follow the operating procedures.
