Product Announcement from DCC Corporation
Portable capacitive discharge (CD) welders are the most popular system employed by users for fabricating thermocouple temperature sensors.
Their ease of use by casual operators and the light weight, small size, minimum power requirements, flexibility and quick welding characteristics make them the favored choice for sensor fabrication in product testing and heat treating applications.
Capacitive discharge units generate a high temperature welding arc so tungsten and platinum high temperature couples are as easily fabricated as more common lower temperature types.
User selectable stored energy levels allow the units to be employed for creating hair wires sized sensors for bio-medical applications and large wire sensors for heavy industry.
With suitable custom fixturing, other weld configurations can be accomplished in a "pseudo-spot-welding" mode.
CD welders are used to attach extension leads to RTD sensors or tungsten filaments, weld screens to backing plates, fabricate multi-cell battery connections, fix studs and nail pins to metal surfaces, connect power leads to resistance elements, attach weldable strain gauges to specimens and many similar non-thermocouple applications.
The simplicity and flexibility of capacitive discharge welding operations offers a good fit to a wide range of engineering requirements.
These welders service a mix of industrial, government, educational, research and development, and regulatory environments.
Starting in 1982, DCC Corporation created a line of welders using straightforward circuit design that both enhance reliability and repairability. The standard components used in the design facilitate repair operations and are readily available when needed.
With DCC's welder offerings, operator control functions are simple and straightforward. Weld initiation is activated by pushing a firing button.
The variable power setting feature supports various wire sizes. Welding operations are performed in the open, so the user can fabricate custom junction configurations or weld the junction directly to metal objects like pipes, tanks, and parts to be monitored or heat treated.
For most applications and sensor wire types, a shielding gas is not required.
