日本近年来对节能问题很重视。据调查,用于手工电弧焊的总电能中,约有40%属可避免的电能损耗,包括电焊机的空载电能损耗、焊接电缆和电缆接头因发热及漏电所造成的电能损耗、用大容量焊机带小负载及由电焊机功率因数低而带来的电能损耗等。据不完全统计,现我国各类手工电弧焊机在几十万台以上,因此应对节电问题引起普遍注意。手工电弧焊的节能,应从节约电
Japan attaches great importance to energy saving in recent years. According to the survey, about 40% of the total electric energy used for manual electric arc welding is avoidable electric energy loss, including no-load electric energy loss of welding machine, electric energy loss of welding cable and cable joint due to heating and leakage, Capacity Welder with a small load and low power factor caused by welding power loss and so on. According to incomplete statistics, all kinds of manual arc welders in our country are in the tens of thousands of units or more, and therefore the widespread attention should be paid to the issue of electricity saving. Manual arc welding of energy-saving, should save electricity
