DC,
Thanks for your reply. I guess our micorwelding is a little different. I weld on tool steel for injection molds. Some of the welds are very tiny where a very small area just needs to be built up 0.005 of an inch or just to build up a sharp edge that has been damaged. We weld on steels such as D2, S7, H13, A2 that is heat treated and hardened
