How to Weld on a MIG Pulse Spray
MIG welding uses a mixture of argon and carbon dioxide shield gases in combination with an electrical arc. The argon forces the metal vapor to ionize, which creates a finger-like penetration in the metal. When carbon dioxide is added, the electric arc's width broadens and makes a shallower, wider weld. MIG pulsed spray alternates between high and low electrical currents. The electrical current creates an arc, which melts the metal welding wire. The molten metal detaches from the tip of the wire and is sprayed out by electromagnetic forces towards the weld pool. Does this Spark an idea?

Set the shielding gas mixture of your MIG to 80 percent argon and 20 percent carbon dioxide. Recess the contact tip 1/8-inch inside of the nozzle so the electrode sticks out 3/4 inch to 1 inch.

Turn on the MIG. Hold the nozzle at a 5 to 10 degree angle.

Push the nozzle tip forward while holding it at a 10-degree angle to the metal. Start to move the tip up and down the joint while moving it slightly side to side. If the metal you are welding is thinner than 1/4 inch move the MIG tip forward and back along the joint, don't move it side to side.
