MMA Electrode Classification - MIG Welding

MMA Electrode Classification. Some rods perform best when used downhand. Some also perform well out of position ie vertical upwards, overhead, vertical downwards, horizontal. The AWS classification (ie E6013 or E7018) doesn't really cater for this, however, the ISO standard does.
