INTRODUCTION The complete range of the capacitor discharge equipment is compact, portable stud welding equipment. The units are specifically designed to enable a small diameter range of ferrous and nonferrous weld studs to be welded to light gauge metal materi‐ als with little or no reverse‐side marking. The equipment consists of a control unit, a welding hand gun, and all necessary inter‐ connecting cables. THE PROCESS Capacitor Discharge (CD) stud welding is a form of welding in which the energy re‐ quired for the welding process is derived from a bank of charged capacitors. This stored energy is discharged at the base of the specially designed CD stud and it fuses the stud to the base material. The time of the weld is determined in such a short du‐ ration that no burn through marking is made on the finish side of the material. CONTACT In contact CD welding, the stud is placed under spring pressure on the material to be welded. When the capacitors are discharged, the special tip of the CD stud melts and the spring pressure forces the stud to fuse with the base material. GAP In gap CD welding, the stud is placed onto the material to be welded. As the stud gun is engaged, the stud lifts from the base material and then returns to the point of con‐ tact at the time of the discharge of the capacitors. As the capacitors discharge, melt‐ ing the tip of the weld stud, the pressure created by the movement of the stud to the base material by the stud gun fuses the stud to the base material. 3 3 3...

SAFETY PROTECT YOURSELF AND OTHERS! Read the safety notices before using welder. ELECTRICAL No portion of the outer cover of the welding controller should be removed by any‐ one other than qualified personnel. Always disconnect the unit from the main power prior to removing cover. This equipment contains a transformer power supply system, which is energized • by AC current and transforms the AC to DC current. Due to potential dangerous electrical input and output the equipment must be disconnected from all incom‐ ing power when servicing. Capacitors store electrical energy. Check for residual charge before performing • any maintenance. Do not use fluids to clean electrical components as these may penetrate the elec‐ • trical system and cause shorts. Connection of the unit into service must be in accordance with the setup procedures as detailed in this manual. Operation of this equipment must be in accordance with all local, regional, and national safety codes. 6 6 6...

SAFETY FIRE During welding, small particles of hot metal can be expelled. Ensure that no combus‐ tible materials are near the welding area. FIRE HAZARD FROM SPARKS PERSONAL SAFETY Arc rays can burn your eyes and skin. Wear protective clothing and eye protection when welding. Loud noises from welding can damage hearing. Wear earplugs or other protective gear, if applicable. Fumes and gases expelled during welding can be hazardous to your health. Make sure welding is done in a well‐ventilated area. Hot metal splatter can cause fires and burns. Wear protective clothing, free of com‐ bustible materials. Have a fire extinguisher nearby and know how to use it. MAINTENANCE All cables must be inspected regularly to ensure that no danger exists from worn or damaged insulation or unsafe electrical connections. Take special note to the cables near the stud gun ‐ this is where maximum wear occurs. Worn cables not only produce inconsistent welds, but can overheat or spark. 7 7 7...

SAFETY TRAINING Use of this equipment must be limited to authorized personnel only. They must be adequately trained, and have read and understood everything in this manual. The manual must be available to operators at all times. AUTHORIZED PERSONNEL ONLY INSTALLATION Select a site for the equipment which is capable of supporting the weight of the equipment, which is clear from traffic routes where people may trip over cables, or they may be damaged by other equipment or vehicles. Do not hang connecting cables over sharp edges or have near heat sources. DISPOSAL The equipment, in its entirety or as components/parts may be disposed of as general industrial waste or scrap. None of the components used in the manufacturing of the CD Welders are toxic, carcinogenic, or otherwise harmful to your health. 8 8 8...

Proper welded studs can be tested by either torquing or bending the stud. The welded flange of the stud should stay in place using either method, even though the threaded portion of the stud breaks. If the base material is very thin, then a full slug, the diameter of the flange will pull from the base metal for a properly welded stud. CD Stud Welding Steps ...
