This is very much a work in progress.

Tools needed:

• One (1) 1/8“ wrench (open-end) (Available in the maint cart)
• Two (2) 1/2” wrenches for work on the MIG gun

Always have two people to change out tanks; it's useful to have extra muscle, or a spotter.

Tanks (both full and empty) are stored against the cages behind the metal lathe.

Tanks in storage must be secured with a chain or ratchet strap.

Tanks in storage:

• 100% argon
• MIG Mix (25% CO2, 75% Ar)

Bottles are labeled with their contents. Make sure you are getting the correct bottle.

Do not move cylinders without a cap on the bottle, securing the valve.

Close the valve on top of the gas cylinder.

If the indicator dials on the regulator show pressure in the system, we must purge the lines.

With the welder unit powered on:

1. Turn down the wire speed and voltage as far as possible
2. Hold the gun far away from the ground clamp
3. Pull the trigger until the dials register no pressure in the regulator.

Cut off extruded wire, coil the gun tube, and stow the gun.

Note: if you have a large amount of excess wire, put it in the box in the powder coat area. The wire is useful for hanging workpieces while powder coating or curing.
