Capacitive Discharge Welders include dual pulse control.
January 15, 2007 -
Advanced Dual Pulse (ADP) welders' functions include current monitoring, programmable pulse polarity, pulse upslope, and 4 selectable pulse width durations. Upslope function can be programmed on pulse to gradually increase the weld energy, alleviating weld splash. Units incorporate 6.5 in. high-resolution color display showing current values, weld limits, and squeeze and hold times, and are available in 100 and 300 W versions.

New Advanced Capacitive Discharge Welders
MONROVIA, CA -January, 2007- Miyachi Unitek announces the release of its next generation of capacitive discharge welders. The new range of Advanced Dual Pulse (ADP) welders has been completely redesigned to provide improved productivity, weld consistency and reliability through features such as current monitoring, programmable pulse polarity, increased repetition rates, pulse upslope and four selectable pulse width durations. The units feature a simplified user interface incorporating a 6.5 inch high resolution color display that shows monitored current values, weld limits, weld counters and squeeze and hold times programmed for each weld schedule, and come in 100Ws and 300Ws versions, with a 1000Ws model to follow shortly.
The peak current for pulse 1 and 2 can be monitored, and limits set for each with the option of second pulse inhibit. This indicates a potential bad weld or process drift, and with the inhibit option can protect against weld blow out. The process monitor shows the percentage of out of limit welds as a percentage of total welds on a quick view bar graph on the RUN screen.
An upslope function, a first on CD welders, can be programmed on the pulse to gradually increase the weld energy to alleviate weld splash.
The programmable polarity function makes it possible to individually select the polarity of pulse 1 & 2, or have alternating polarity for successive welds. This can be used to provide a uniform weld nugget size under both electrodes and more even electrode wear resulting in reduced consumable costs.
With an innovative new charging unit, the repetition rate of the ADP welders has been increased by 30-50% over the current units' range. This offers maximum weld throughput for both manual and automated setups.
Resultant of increased component miniaturization and the need for improved weld optimization; 'Very Short' (VS) pulse duration has been added to the new units. The four pulse durations are now spread more evenly than on legacy units to offer an increased range of weldable materials and parts. The pulse times were selected to ensure that these new durations overlap the current range of DP welders for ease of integration and retrofitting.
Founded in 1948, Miyachi Unitek designs and manufacturers a full range of resistance welding and reflow soldering power supplies, heads, monitors and accessories for both large scale and fine spot applications.
