Request Information

The HotSpot II is a heavy duty capacitive discharge welder for forming freestanding thermocouple beads. It can also weld thermocouples to metal surfaces or attach supporting hardware and small gauge studs. 

This unit will weld wire pairs as heavy as #14 gauge. It can close larger tubes than the standard HotSpot welder and perform light duty stud welding as an aid in wire harness attachment and insulation blanket installation.

In the box: HotSpot II welder, standard pliers with quick connect end, heavy-duty magnet, knob, carbon block, eye shielding goggles, and instructions.

Front panel indicators and controls allow the operator to easily monitor the status of the unit, determine the level of energy to be stored, and initiate a weld cycle.

The power level is set by the position of the front panel control knob.

The power ranges, normal (low) and turbo (high), are selected by a two position toggle switch. Peak voltage on the low range is approximately 35 VDC and on the high range 75 VDC. 

Initiation of the welding discharge is controlled by a snap action push button switch.


The range switch and power level control set the voltage to which the energy storage capacitors are charged. The stored energy is proportional to the square of the capacitor voltage. Increasing the setting of the control knob will cause the capacitor to be charged to a higher level. However, decreasing the setting will not immediately reduce the value already stored so a welding cycle will always release an energy pulse equal to the highest power setting since the last recent discharge.

A resettable circuit breaker in the primary AC line is accessible on the unit's back panel and protects against damage from internal circuit shorts and similar fault conditions.

The HotSpot II welder is a dual range high-energy unit that has the versatility to provide fine control as well as the high power capability needed for heavier wires. It can handle wire pairs as heavy as #14 gauge. The HotSpot II can also close larger tubes than the standard HotSpot and can do light duty stud welding as an aid in wire harness attachment and in insulation blanket installation.

The HotSpot II is powered from the AC line through a step-down transformer and rectifier. Front panel indicators and controls allow the operator to easily monitor the status of the unit, determine the level of energy to be transferred to the storage capacitors, and initiate a weld cycle. The maximum power output of the HotSpot II is approximately 250 Joules. The power level is set by the position of the front panel control knob.
