Answer: The electric welding machine can work continuously without stopping under the current value of 100% load holding rate. If the rated continuous rate calibrated by the welding machine is not 100%, the current value at 100% load holding rate can be obtained through conversion. The welding current used for different load continuity rates is listed on the nameplate of the welding machine, and it shall not exceed its specified range when used. For example: 8KW welding machine uses ?2.5mm electrode, 11KW, 16KW welding machine uses ?3.2mm electrode, can work all day.
