10 DEPOSITION RATE The deposition rate describes how much usable weld metal will be deposited in one hour of actual arc-on time. Because the mig process is very efficient, only a very small amount of weld metal is lost as spatter. The deposition rate for any wire is calculated by the equation: (m/min) deposition rate(lbs./hr.) =     wire feed speed  (in./min.) x 60 min./hr. (kg/hr) inches of wire per lb.
