Can the welding line of AC welding machine be dead?
Electric welder no-load voltage in 50V ~ 90V, and the highest level of safety voltage 42V, no-load voltage is higher than the safe voltage, this is not the main safety factors of two lines; in addition, the general electric welding arc ignition, working voltage 16V ~ 35V needed to maintain the arc, although in a safe voltage range but, in the bad environment such as welding on metal structures, metal containers, pipes or under water and wet locations for welding, welding if the poor body condition, body resistance is very low, may cause electric shock, safe voltage is not absolutely safe.
In fact, if we discuss the electric shock of the two wire from the wider range, the harm to the human body is varied. The human body in the welding process in contact with the two line, the current acting on the human body in the contact area will produce electricity burns, electric brand or the central nervous reflex and strong muscle contraction caused tissue fracture and fracture mechanical injury; arc welding process, the industry protection is not the time, can make it happen an eye disease or make the metal particles penetrate the skin causing skin metallization; in addition, there is a more severe shock.
The welding line of AC welding machine is the two line of electric welding machine.The welding wire caused by electric shock accidents, because the two line is low voltage (no-load voltage generally 50 - 90V), people understand the causes of electric shock, often mistakenly think that the welding line two times is "safe", leading to accidents causing death two line not uncommon a shipyard is a young female welder, welding is the cabin, the cabin due to high temperature and poor ventilation, body sweating, canvas overalls and leather gloves are wet. When replacing the electrode holder when touched, because of spasm fall backward, falling out of the neck in the holder, failed to cause electric shock accident died after death. The accident tells us that the two line voltage of the welder is low, but it is enough to kill.
