[PDF Version]FAQS about Capacitor energy storage pressure resistance welding
What is capacitor discharge resistance welding?
Capacitive discharge resistance welding uses large capacitors to store energy for quick release. Figure 1 shows a typical capacitor discharge curve. Capacitive resistance welders have many advantages. Weld nugget formation takes place during the first few milli-seconds.
What are the advantages of a capacitive resistance welder?
Capacitive resistance welders have many advantages. Weld nugget formation takes place during the first few milli-seconds. Capacitive discharge welders allow extremely fast energy release with large peak currents. More of the energy goes into weld formation and less into heating surrounding material.
What is a capacitive welder?
Capacitive welders deliver repeatable welds even during line voltage fluctuations. Spot welding relies on the principle of metal resistivity to heat and fuse metal. A large current is passed through the work piece. Energy is dissipated due to the metal resistance in the form of heat which melts and fuses weld materials. There are two phases to
What is a capacitive discharge welder?
Capacitive discharge welders allow extremely fast energy release with large peak currents. More of the energy goes into weld formation and less into heating surrounding material. The heat affected zone, where the properties of the metal have been changed from rapid heating and cooling, is localized to a small area around the weld spot.
Can a welder use an external power supply?
When using alternate external power supplies it is critical that the user does not exceed 18VDC into the fast charging port. Doing so will damage the welder and void its warranty. Sunstone Engineering produces a variety of welding hand pieces and weld heads to accommodate a diverse range of welding applications.
How does electrode pressure affect resistance welding?
Using more electrode pressure creates more metal bridges. This results in a lower contact resistance and cooler weld. Conversely, light electrode pressure results in less metal contact, higher resistance, and a hotter weld. Figure 3 shows several different electrode configurations used in resistance welding.
