Prior to Welding

Prior to Welding:

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

# Ensure the adjusting screw on the tank regulator is loose (Do not unscrew 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.

# Slowly turn the adjusting screw (clockwise) to increase pressure to 15 CFH. At first it will spin freely but you will begin to feel resistance as the pressure begins to increase on the leftmost pressure gauge.  

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

# Identify the material type and thickness that you will be welding.

# 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 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

# Ensure you are wearing all necessary protective gear. This should include closed shoes, pants, a welding coat, a welding helmet, and welding gloves. There should be no skin exposed to the welding arc or it will cause burns.

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

# Ensure the welding torch has proper amount of wire protruding from tip (about ¼ inch) and that the torch nozzle is clean of any debris. You can use pliers to scrape off any debris in the nozzle. If too long, trim excess with the welding pliers. If to short, pull the trigger while the torch is not in contact with anything and more wire will be fed out.

# Weld!   

 

# Set up the work pieces in your desired configuration. Magnets and metal clamps are helpful for doing this and can be found on the tray below the tabletop.
