==Description==

The Millermatic 210 is a wire feed metal inert gas (MIG) welder that is meant for light industrial use. Metal inert gas is a welding process in which an electric arc forms between a consumable MIG wire electrode and the base metal, which heats the base metal, causing them to melt and join. Along with the wire electrode, a shielding gas feeds through the welding torch, which shields the process from contaminants in the air. This is the easiest and most common type of welding which makes it perfect for those learning to weld. It uses 72/25 CO2 and Argon gas mixture to shield the molten weld from oxygen. If the weld pool is exposed to oxygen, it can create a handful of problems such as porosity and excessive spatter in the bead. This welder is capable of welding carbon steel as well as stainless steel. Below is a short video explaining MIG welding.{{#evu:https://www.youtube.com/watch?v=twUAa5LWUvk}}

Before completing the training on this machine you must complete the [[Virtual Reality Welding Station]] training and spend some time practicing with it to get a feel for the welding process.

====General Procedure====

Prior to Welding

Prior to Welding

# Place the fume hood over the area you will be welding at

# Place the fume hood over the area you will be welding and make sure it is on. The power switch is located on the wall next to the door and light switch.

# Attach the ground clamp to the bench your workpiece will be on  

# Attach the ground clamp to the metal bench your workpiece will be on. Ideally, place the ground clamp to the base metal itself to create the smoothest path for the electrical current.

# Ensure the workpiece is touching the conductive surface of the table

# Ensure the workpiece is touching the conductive surface of the table

# Ensure the adjusting screw on the tank regulator is loose (Do not unscrew all the way)

# Ensure the adjusting screw on the tank regulator is loose (Do not unscrew all the way)

# Identify material type and thickness that is going to be welded

# Turn on the welder and adjust wire speed and voltage

# Turn on the welder and adjust wire speed and voltage. Refer to the image below to see the controls for doing this. [[File:MIG Controls.png|none|thumb|837x837px]]

# Ensure you are wearing all necessary protective gear

# Ensure you are wearing all necessary protective gear

# Ensure the welding torch has proper amount of wire protruding from tip (about ¼ inch) If too long, trim excess with the welding pliers.
