Capacitive Discharge (CD) resistance welders have many advantages over other welder types. CD spot welders are generally more affordable. Operators also achieve quick energy release for welding highly conductive metals such as copper. This quick energy release is concentrated into a small area, generating only a small heat signature or heat affected zone (HAZ). This small HAZ means that more delicate projects such as welding a battery will maintain the integrity of the cell’s chemistry when using Sunstone’s Dual pulse CD spot welding technology.
The Dual Pulse feature is ideal for achieving strong weld joints. Dual Pulse is another way of saying that a given stored energy level can be allocated or divided into two separate pulses that occur within milliseconds of one another. Pulse 1 is a low energy pulse designed only to pre-heat the weld part, and does not actually perform the weld. This pre-heat pulse has a few advantages: it seats the electrodes, helps to eliminate weld splash, and aids in burning away contaminants and oxides. Pulse 2 performs the actual weld by discharging remaining stored energy for permanent nugget formation.
Sunstone spot welders are simple to use with an intuitive and user-friendly interface. Each of the Dual Pulse CD welders can be adjusted and fine-tuned to match the requirements of countless applications. A digital screen displays total weld energy and individual pulse length settings, ensuring detail and precision. When combined with Sunstone’s new line of weld heads or hand attachments, CD welders perform strong and repeatable welds for high levels of consistency and quality control
