Of course, if you're doing this to an axle nut, it ruins the heat treat and=
 it (the nut) has to be thrown out and replaced. =A0For bearing race, the h=
eat might be a problem, but on the nut, with a fully assembled hub, the the=
rmal mass and gradient is so high that it gets sucked out before it gets ho=
t enough to affect any heat treat that might be in the axle or hub. =A0I do=
n't know if MIG would work, never tired it, but it might lay down too much =
metal and interfere with getting the wrench on. =A0MIG is preferred of cour=
se and with stick it is doable with very thin rod at about 75A. =A0Any more=
 and there is a chance to put in enough heat to cause problems. 		 	   		 =
