The HotSpot Capacitive Discharge Welder is designed to help solve your thermocouple fabrication and attachment problems. The welder generates an electric arc for fusing standard couple elements into freestanding beads and welding them to any thickness base metal. Visual and sonic indicators alert operator when the welder has cycled and is at the user selected power level. 

The HotSpot welder is powered by a gel type battery, which provides power for a few hundred welds. The battery is automatically recharged whenever the unit is connected to AC power. The unit can also be operated directly from the AC line.

Merging creation of thermocouples with direct attachment to surfaces, the HotSpot provides advantages in cost, flexibility, accuracy, and the time required for installation.

The principal difference between the HotSpot II and the standard HotSpot is its heavier wire welding capability. The HotSpot II can handle thermocouple wire pairs as heavy as #14 gauge. It can also close larger tubes than the standard unit and can perform light duty stud welding as an aid in wire harness attachment and in insulation blanket installation.

The HotSpot II operates only from AC power. Its lightweight compact design makes it a very portable welder.

The HotSpot PLUS offers heavier wire and stud welding capability along with single hand operation and an optional foot control. The HotSpot PLUS can handle wire pairs as heavy as #12 gauge and studs lighter than #10. It can close larger tubes than other HotSpot welders and perform stud welding as an aid in wire harness attachment and insulation blanket installation.

The HotSpot PLUS operates only from AC power. Its 18lb compact design and optional accessories provide flexibility for field and bench applications.
