The machines can be both manual and computer operated.
Manual welding machines are normally portable and can be used to connect (weld) 2 pieces of metal, normally steel together. They doe this by melting both contact edges of the metal together to make on very strong joint.
Auto welders are more robotic. Frequently seen in the car are white goods industry, the machines are pre-programmed to place welds exactly in the same place many hundreds of time. These may be full seam weld as in a join or tack welding where spots are selected on the body to be joined and a one of spot joint is made.
An AC welding machine is one that uses electrical power from house or shop and has a controlled output in AC or Alternating Current.
Transformer type welding machine
Three phase uses a safety circuit away from the machine, two phases uses you as the safety circuit

Digital Control of welding when welding
A rectifier is a type of welding machine. Fairly new development that changes common electrical supplies to voltage and amperage that can be used to weld. It uses less electricity than standard welding machines (usually transformers). It will require a certain supply (voltage - amperage) that you connect the machine to and should state the minimum requirements somewhere on the machine.
A welding machine rated at 500 amperes uses around 120000 watts of power. This is used in very heavy industrial applications due to its large power draw.
metal inert gas (MIG) welding
Welding machine companies are important, because welding machine manufacturers like Artech Welders, Dynarc Systems, Crystal Electrodynamix are provides all types of welding machines for various business firms.
TIG welding uses Argon.
