How many meters should the length of the primary side power cord of the Hydrogen Oxygen Flamer not exceed?

3 meters. According to the mandatory national standard "GB9448-1999 welding and cutting safety" Article 3.1.5.3: the primary power cord of the welding machine, the length of the general should not exceed 3 meters. So the length of the primary side power cord of the hydroxyl flame machine should not exceed 3 meters. Hydrogen-oxygen flame machine is the use of electrochemical principles, the conversion of alternating current to direct current, the machine electrolyzer in the water decomposition to produce hydrogen and oxygen, hydrogen as a fuel, oxygen combustion, ignition to form a hydrogen-oxygen flame machine equipment.
