The HotSpot and HotSpot II are portable, capacitive, discharge welding units that allow thermocouple wires to be formed into freestanding beads or directly welded to metal surfaces for temperature sensing. Direct bonding avoids the need for clamps, brackets, straps, and welded wells, and provides a quick, simple, accurate, low cost means, of attaching thermocouple sensing wires on a "when needed", "where needed" basis. The HotSpots are equally effective in forming freestanding bead or butt-welded thermocouple junctions. It takes only seconds to form standard thermocouple wire into a variety of attached or unattached sensors.

THE HotSpot SOLUTION:

SIMPLE - Thermocouples are formed directly from standard wire types as either freestanding or surface mounted junctions. Solves the waiting problem in making and attaching thermocouples.

EASY - Installation does not require skilled operators or prepared surfaces. FAST - Pre-planning for the thermocouple fabrication or attachment becomes minimum, since welds can be quickly made whenever and wherever they are needed. Takes only seconds to go from standard TC wire to welded thermocouples.

ECONOMICAL - Installation and material costs are low, allowing redundant junctions to be provided without incurring significant additional costs.

ACCURATE - Welded junction provides an accurate thermocouple having a high-speed response characteristic. Beads can be made to desired size.

ADJUSTABLE - Front panel power control provides adjustment for handling various thermocouple wire sizes and materials, simplifying operator training and use.

HUMAN ENGINEERED - Visual indicator alerts operator when unit has recycled following a weld, and a new cycle can be initiated.

THE HotSpot IS SUITABLE FOR:

• Field use, where its small size and ease of handling provides the flexibility needed for such environments.
• Shop use, where the size or shape of a piece to be treated dictates that the temperature sensors be directly installed on the work. To make sensors for heater and oven control. For attachment of simple fixturing hardware. Considerable time and energy savings can be made when the temperature is accurately known.
• Lab and pilot run use, where the ability to immediately install thermocouple junctions anywhere, makes quick changes and additions to experimental or test set-ups easy. Freestanding junctions on wires of any length for general temperature tests, are easily produced.

Give up waiting for prefabricated thermocouple junctions and weld your own sensors with the HotSpot and HotSpot II.
