英语翻译
The intense heat at the electrode tends to melt off the end of the electrode and contaminate the weld.Hence,for any given current DCRP requires a larger diameter electrode than DCSP.For example,a 1/16" diameter tungsten electrode normally can handle about 125 amperes in a straight-polarity circuit.However,if reverse polarity is used with this amount of current the tip of the electrode would melt off.Consequently a 1/4" diameter electrode would be required to handle 125 amperes of welding current.

焊接时,电极端剧烈的放热有可能使电极熔化,进入熔池,污染焊缝.因此,直流反接焊接时比直流正接时的电极直径要大.例如,1/16 英寸的钨电极一般电流可达到125A.然而,该电流值不变,变换电极极性,钨电极可能会熔化.因此,这种情况时要使用1/4英寸的电极.
我是专门搞焊接的,这上面将的其实很简单.主要针对的是TIG焊.简单来说直流反接时的电极要比直接正接的粗些.1/16 "≈1.6mm 1/4 "≈6.4mm
