# 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. This is critical if the clamp is not touching the base metal.

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

# Open cylinder valve all the way

# Slowly open cylinder valve all the way. Suddenly opening the valve could cause damage to the regulator.

# Turn the adjusting screw (clockwise) to increase pressure to 15 CFH.

# Refer to MIG welding chart for specified adjustments, specific to your application

# Determine the wire feed rate and voltage to fit your material and wire size. To do this, refer to MIG welding chart for specified adjustments specific to your application. A welding chart is included below for reference and the same chart is mounted inside the cover of the welder. [[File:Welding Chart.png|none|thumb|706x706px]]

# 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]]

# Turn on the welder and adjust wire speed and voltage to match the parameters layed out by the welding chart. 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
