thermocouple connection

How do you connect a thermocouple to the thermocouple wire?
Can I solder the wires?
Use copper lug?

Copper lug
I donít want to create another junction but I donít have an approved connector

You are awfully close to the heat to use wire nuts. Split bolts would actually do pretty well given the proximity to the heat. It's not conventional but I don't know that it matters.

Things to know. Red is negative. You have to use thermocouple wire that is the same as your probe. Split bolts will work twisting wires together in a wire nut will not give accurate readings. You can strip some of your thermocouple wire twist the very end and either snip it close to the end or preferred weld together with a torch. You now have no connections to worry about. If your thermocouple wire is thin you can make a sheath to go in the kiln from glass or ceramic. This will help reduce tempature swings when you open the kiln.

I made the mistake of thinking I could make money at a little show in a rich town near by. The promoters failed to bring out the people. So I sit here with time on my hands waiting for 5:00 to come. I should know better.

Life is littered with bad shows. Sixteen minutes to go. Even now When I'm in high anxiety level I have dreams of doing a show where I did not sell a single thing and at the end discover that someone has thrown out all my boxes and packing.

Sky is correct about the lead wire having to be a match to the thermocouple wire. If your thermocouple does fail, in a pinch, twist the two wires together very tight at the probe end and you'll have a short term thermocouple that is fairly accurate.

Thanks for the replies. The thermocouple wire is the thermocouple itself which is very thick and stiff. The connecting wire is very thin and flexible.
I like the idea of welding but may need to unscrew for repair and testing the circuit if the readings go wacky.
Hope I can get small split bolts.
Sky sorry to hear about your show. Now you have the hardestT part. Packing up.
Glad you mention the color. Everyone knows red is positive.
We donít have shows.

Just wanted to clarify one thing. The only welded connection allowed is the tip of the thermocouple. You can not weld or twist any connections between the thermocouple wire and the thermocouple.

Pete you definitely gave me a chuckle and helped the packup.

Thanks Sky. Yes the joining I am talking about is the thermocouple to the thermocouple wire. The problem is the thermocouple wire is very thick and stiff and the thermocouple wire I have is very thin and flexible. So I twist it around the thicker wire and use a screw it to keep in place. I may have to cut my own split bolt. They have big split bolts.
So far I am getting away with the screw it connector.
George the electrical shop said eh.?

This type of connector provides a bridged connection with set screws on each side so you can connect different sizes of wire together. Connect the thermocouple poles to one side and directly across from each pole connect the thermocouple wires. The ceramic body provides electric isolation for each pole and surroundings it can also be mounted with a center screw.Here is copy to a PDF you can share with your electric shop. Hope that helps.

Here is another site with ceramic connecting blocks for thermocouples. EUSTIS/Pyrocom
