Page 7: Material Preparation
WeldTech - Hot Air Welder Instruction Manual The latest trend in developing electronic controls for hot air heating elements incorporates closed loop controls that hold the temperature constant even while air flow or supply voltage fluctuate. An equally important factor in hot air welding is the style and type of welding nozzle (tip). -
Page 8: High Speed Welding
WeldTech - Hot Air Welder Instruction Manual 2.5 HIGH SPEED WELDING As far as hand welding is concerned, more than 90% of the structural welds are high speed welded. In this process a filler material, the welding rod, is introduced into the seam to give supportive strength. - Page 9 WeldTech - Hot Air Welder Instruction Manual 3. BEAD FORMS There are a great number of bead forms that can be specified; most common ones are shown on the following page. Certain aspects must be taken into consideration before starting to weld. A smaller diameter welding rod is preferable to a large one since it is easier and faster to control the plasticizing process.
