When MIG welding mild steel, you can use either the push or pull technique, but note that pushing usually offers a better view and enables you to better direct wire into the joint.

Titanium has to be very clean from oil, grease, coatings, and oxides before welding takes place.
MIG Welding: The Basics for Mild Steel
I kept using the same voltage, but with a slightly lower wire speed. If you put the gun down for awhile, you can be sure the shielding gas has escaped. That should be the goal. A slight weaving motion can help control the size, shape and cooling effects of the weld puddle. True, you will not use the same wire speed for different wire sizes, but your weld amperage is a direct function of your set voltage relative to your wire speed. Pushing usually produces lower penetration and a wider, flatter bead because the arc force is directed away from the weld puddle.
