I use 7014,mostly,6011 also.They make a 7018 for AC,I have tried it and it is OK.It doesn't hurt to have an oven for welding rod in general[my shop ain't heated].A piece of 6" pipe long enough to hold the rod with a door on one end and a plate with a lite fixture on the other and a 40 watt bulb.You can build it with what ever rod you decide to use.
