When welding with a M.I.G. welder, keep the gun steady and the wire extended 3/8th of an inch long. Never look at a spark light from a welding gun without proper eye wear, same with cutting torches. Try to keep yourself covered with safe welding gear (recommended but not necessary) like a leather jacket, welding gloves, and protective goggles or glasses. Also use nosel gel on the tip of your welding gun of a M.I.G. welder.
