Editing Instructions:Miller Millermatic 212 Autoset MIG Welder (section)

=== Procedure ===
'''Work Angle'''-angle of the nozzle relating to the joint and piece. Should point directly into the joint.

'''Travel Angle'''-angle of the nozzle relating to the direction of travel. Can be 10-15* in a push or drag angle.

Using both hands on the gun, position yourself comfortably and sturdily, with your supporting arm or hand resting on something solid. Adjust your hands so the nozzle is pointing into where you want to weld, and your travel angle and work angle are appropriate. Rehearse your weld and make sure you don't get caught on anything, that your angle doesn't change towards the end of the weld, and that you can reach where you need to weld.

Pull the trigger and begin moving. Be aware of the puddle just behind where the brightest arc is and how much of a bead is forming, and adjust your speed as needed. Slower will cause a larger weld and retain heat and penetrate deeper and may cause holes. Faster may not fill up enough and cause undercut, or just sit on the top and not fuse.

If you find there is porosity in the weld, confirm or adjust your gas settings, and make sure the workpiece is clean of all grease, dirt, or paint.
