Adjust the hot air gun to the proper temperature setting and direct the gun to the point where the weld seam will be started on the edges of the belt ends. The tip of the hot air gun should be in close proximity of the belt splice area (approximately 3/4 " - 1 ") and the heat flow directed so that it will penetrate the beveled area of the belt and weld rod at the same time.

Maintain pressure against the weld rod to cause a radius of the rod and force it into the beveled seam area. Force the rod downward to reach the bottom of the carcass. Keep the flow of heat directed in a manner that will heat the beveled edges and the underside of the weld rod simultaneously (See illustration).

The NOVITANE belt cover will develop a gloss at the proper fusion temperature and the welding rod surface will become pliable and viscous. Draw the heat gun and weld rod towards you while you point the heat flow in the opposite direction and proceed to weld the seam.

We recommend the use of the small diameter round weld rod on the first pass to the very bottom of the carcass. Then, weld directly over the rod with either the 5/32 " or 1/4 " triangular shaped weld rod depending upon the overall belt thickness to overfill the beveled gap.
