A completely revamped product design for Servo Motor Guns. Modern and novel design, minimum parts and ease of maintenance. Possibility to integrate a built-in force sensor for closed loop force feedback are the highlights of this generation. MAIN FEATURES Design - TECNA Robot guns are designed as per European standards. The unique design can accommodate motor from any robot manufacturer. The compactness, user friendliness and maintainability of Tecna manual guns is earned forward to Robot guns design too. Every part or subassembly of the gun is subjected to life cycle test before accommodating into the product. Modular design enables standard parts for all guns. Product Range - As per TECNA's philosophy of optimisation ,AC robot guns are available in 32 KVA, 36 KVA, 54 KVA, 60 KVA, 75 KVA. MFDC guns are available in 56 KVA and 90 KVA. Increase in productivity - The electrode opening can be precisely controlled and travel distance between the spots can be reduced. This results in reduced spotting and traveling time. The electrode opening position can be defined for each spot reducing the opening and closing time of electrodes resulting in reduced spotting time Precise control on Welding Force - As The welding force is controlled by Current utilized by servo motor, actual force while welding can be controlled precisely. Welding force for each spot can be programmed as per welding requirement of different combination of sheets to be welded. Inbuilt Force Transducer - To receive real time feedback of Force while welding is also available as option. This is achieved by integrating a Force Transducer built inside the gun mechanism. Precise control on Heat Generated ( Energy Consumed) while welding - Three important parameters of welding are Current, Time and Resistance. With TECNA constant current secondary feedback Welding Control, Current and time are precisely monitored. The contact resistance is dependant on actual force applied while welding. Servo system controls the force accurately resulting in generating required Heat for welding. Soft Closing - Electrode Closing speed is reduced just before they touch the panel. This results in reduced Dents and increase in electrode life as initial impact of electrodes is avoided. Correct welding position - This servo system can identify Tip wear, Deflection in arms and tip position. This helps for correct welding position of the gun.

MAIN FEATURES There are applications and situations where the MFDC resistance welding is the best choice available. Although there are significantly higher initial prices, the overall cost of using MFDC over single and three-phase SCR control may actually be significantly lower. Significant Energy Savings - For plants that cannot purchase more electrical power, the MFDC approach may allow you to do more projects with less energy. lmproved and Consistent Power Factor - The MFDC load appears to have unity power factor, which would then reduce penalties assessed by the power company. Automatic Load Distribution - The MFDC load is evenly distributed across all three phases. The bank of capacitors that are found on the MFDC system allow for current to be drawn from the bank as well as from the line thus reducing peak line currents. Welding is Tolerant of Electrical Line Disturbances - The energy reserve of the capacitor banks will smooth out line notches and line spikes even while welding is taking place. Precise Welding Current Control - The MFDC utilizes IGBTs for switching. These are turned on and off at the rate of 400 to 2000 times per second. By controlling both the turn on and turn off, the MFDC can determine the current to control. Conventional controls utilize SCRs for switching. These are turned on by the weld control but then remain conducting until the line voltage crosses the zero point during the base frequency line cycle. Because of this, conventional single phase controls must use a predictive algorithm rather than a deterministic approach. Also, if an under or over compensation occurs on one of the cycles, the conventional AC control will have to wait until the next period of the base frequency whereas the MFDC need only wait a fraction (1/20th nominal) of that time. Attains Target Current Immediately - DC systems of the SCR type have a rise time prior to its steady state. Since the MFDC is so responsive, it is possible to create full phase firing during the natural rise time to lessen that period of time. More Process Friendly - The MFDC eliminates undesired inter-cycle cooling periods that exist in AC resistance welding processes. Welding therefore can occur faster which would then reduce heat waste and the problems associated to eliminating that waste. Low Inductive Loses in Secondary Circuit: Due to DC current, the inductive losses in secondary circuit because of the magnetic metal content in between secondary circuit are minimized giving accurate control on welding current. Higher Current Deliveries : lmproved short circuit currents up to 30 KA are useful for welding materials like Brass, Copper, and Aluminum. Lower Cycle Times : As the welding periods are in milliseconds and inter cycle non activity is avoided, thus cycle time of weld is reduced resulting in higher productivity. Lower Weight and Size of the equipment : This increases the maneuverability of the machine resulting in reduced fatigue to the operator.

Welding is a power hungry process. Be it in any form. Optimizing power consumption in Resistance Welding Process has never been more effectively addressed than these machines. This is possible because of specially designed transformers. They have very low secondary voltages and very high thermal currents. Low losses also mean lower internal heat generation and as such lower cooling water requirement. Modular design, commonized spare parts are part of the design philosophy.
