Thermocouple Welding and Soldering
- This model is suitable for welding wires up to 1.1 mm (0.043') in diameter and has an argon gas shield facility. A satisfactory thermocouple junction is produced without using argon, but where argon is available a momentary purge is automatically triggered immediately prior to the weld to give optimum weld integrity.
- 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.
- This instruction manual describes how to operate, maintain and service the Thermocouple Welder, and provides instructions relating to its SAFE use. Procedures described in this manual MUST be performed, as detailed, by QUALIFIED and TRAINED personnel.

Thermocouple Welding and Soldering

I am looking for an information source about welding and soldering Type T thermocouple (T/C) extension leads to another extension lead and also to the thermocouple wire.
Specifically information regarding the technique, sources of error, and the pro/cons of welding vs soldering.
Why is there a special procedure/technique for welding Type T and what is the special process?
Does anyone have experience with either technique?
BACKGROUND
We have 68 Type T T/C channels located outside in New England. We currently have Omega MTC-12 connectors mounted on masts with the male connector on an umbilical to the T/Cs. The female bulkhead connector is mounted on a 4x4 enclosure. The female bulkhead mount (admittedly) does not have the specified environmental backshell. As expected we are experiencing erroneous readings and open T/Cs. The connections should not have to be undone for 20-30 years. I would like to propose removing the connectors and welding or soldering the T/C cable wires at the connection at the 4x4. Also, I would like to weld or solder the extension cables to the industrial T/C leads at the T/C peckerhead.
PS: Does anyone have a better name for the 'peckerhead'?
HotSpot II Thermocouple WelderThe principal difference between the HotSpot II and the standard HotSpot is its heavier wire welding capability. The HotSpot II can handle wire pairs as heavy as #14 gauge. It can also close larger tubes than the standard unit and can do light duty stud welding as an aid in wire harness attachment and in insulation blanket installation.Specifically information regarding the technique, sources of error, and the pro/cons of welding vs soldering.

The HotSpot II operates only from AC power. A battery-powered version of the unit is not offered. Its less than #14 weight and compact design make it a very portable package.
QUICK ACTION The HotSpot II is light and portable so you can move it right to where you need to make and attach thermocouples. The actual welding time in less than a second and the short recycle interval, even at full power, will allow you to make 6 or more welds a minute.
ECONOMICAL Making and installing thermocouple junctions using DCC's HotSpot II is extremely economical. Freestanding beads can be fabricated or junctions welded to fixturing hardware or directly to the surface being sensed, at the rate of 5 to 10 a minute. There is no need for elaborate set-ups or specially trained operators. Skip the pre-planning, expense, and delays involved with purchasing thermocouples outside or having them made through another department.
EASY-TO-USE Anyone can quickly become proficient in the use of the HotSpot II. While sophisticated internally, the HotSpot II provides the operator with a firing button and a simple on/off and energy level adjustment. A weld is generated by holding the bared end of the thermocouple wire to the bead forming graphite electrode or the surface to be sensed, while pressing the firing button.
FLEXIBLE 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. Front panel indicators and controls allow the operator to easily monitor the status, set the energy level, and initiate a weld cycle.
