Recently I was Arc-welding 1/2 inch steel with an amperage setting at 
150Amps.  I was wondering sence high amperage eletrity creates a magnetic 
field and the steel is molten when welding, why dosent the steel move 
around in the magnetic field? Example puddle of steel coming towards the 
electode.  Is it because theres not enouf amps or why?
