Properly introducing filler metal into the welding puddle is an important component of laying a proper weld bead. Introducing filler metal too quickly can result in the base metal overheating, while introducing filler metal too slowly or in insufficient quantities can result in little more than an etch on the base metal. Furthermore, it's important to maintain a balance between the heat, which you are applying with the welding torch, and the amount of filler metal that you are adding. Too much heat will cause you to lose control of the welding puddle, while too little heat will result in the welding puddle drying up.

1
Hold the filler rod in a 90-degree configuration to the torch.

2
Push the torch forward and introduce the filler rod on the leading edge of the puddle. Keep one hand smooth and steady as it slides; dab the filler rod, with the other hand, into the puddle.

Add filler metal consistently to the puddle. Add it in rhythm with the movement of your welding torch after you find a speed at which to add filler metal that keeps the welding puddle moving forward, but in control.
