1. Grab safety equipment and tools:

   1. Helmet, glasses, and gloves

   2. MIG pliers; wire brush

   3. MIG gun holder

2. Open main gas valve (top center)

3. Turn on the machine on the back right top

4. Adjust the flow meter (small pin)

   1. Pull the trigger to activate gas

   2. Adjust flow valve to ~20 cfh (cubic feet per hour) or 10 LFM (linear feet/minute)

5. Adjust power / feed settings → Multimatic will automatically select wire feed speed (WFS) and voltage

   1. Select process based on material - (Standard = MIG Steel C25 = 25% CO2 + 75% Argon)

   2. Select wire size (Standard 030)

   3. Select thickness of material

      1. Use metal gauge in CNC plasma cabinet

6. Attach “ground clamp” to the material / table

7. Confirm material is clean (wire brush)

8. Practice welding movement path

9. Check area for hazards

10. ALERT people in the area that you are about to weld — say “WELDING”

11. Start welding!

1. Finish welding for the day but keep the machine ON

2. Close the main gas cylinder valve (or the tank will empty on its own! = expensive and unnecessary)

3. Pump the MIG gun trigger to bleed the pressurized air. The cylinder pressure gauge and flow meter should drop to zero

4. Trim off excess feed wire

5. Back out the flow meter screw until it is loose and free spinning

6. Turn off the power source

7. Trim any excess wire and put away all tools
