Children with microcephaly often have developmental issues. Generally there's no treatment for microcephaly, but early intervention with supportive therapies, such as speech and occupational therapies, may help enhance your child's development and improve quality of life.
Spool of .035 Aluminum Welding Wire is used with 100% argon gas. This is a 8 diameter spool with a center mounting hole that is standard 2 diameter. This wire is also great in a spool gun. Note that this is precision wound wire, verses random wound.
A: I would like to answer your question as a general discussion of flux-cored welding. The American Welding Society (AWS) classifies all tubular electrodes having a flux on the inside as flux-cored wires, and calls it the Flux Cored Arc Welding (FCAW) process. All flux-cored wires have some similar characteristics. These include forming a protective slag over the weld, use a drag angle technique, have the ability to weld out-of-position or flat and horizontal only at higher deposition rates (depending on type of wire), ability to handle contaminants on the plate, etc.
