Yes, I did see that! There are only 4 connections - 2 for the coil, and 2 for the On/Off switch contacts, so I don't think it matters that the relay is upside-down!
However, regarding the "always-on" overheat warning light: this implies that the mains wiring has been messed with.
The warning...
If the relay is new ( and it is the correct part ) but the welder only turns on when you manually short across the relay contacts, that implies the relay was never at fault. It is probably not getting triggered on. The circuit that activates the relay coil is fairly simple, and starts with the...
Post #13 of this thread mentions a "Carl Horton" at Horton Welding Supplies who knows all about Butters machine:

As Dragnet said, an oil-filled or an air-cooled arc welder can be used as a power source for the TIG add-on box. Both types are heavy, so I would suggest looking locally for a s/h unit, on eBay or Gumtree etc. They normally go for between ten and one hundred Pounds... A simple cheap unit will...
Yes, it is a rectifier. It changes the AC output of a simple transformer-based arc welder ( also known as a "buzz box" ) to DC for use as a TIG.
When used in this way, an arc welder is called a "power source". That is the missing component, and that is where the amperage would be adjusted.
The...
The thermal shutdown light is "On" if the overtemp cutout switch is open-circuit. This should only happen if the welder has been used at high power for a long time, so it implies that the cutout switch is faulty and has gone open-circuit permanently. When open, the light will be on and the...
There is a circuit diagram in the first post of this thread:
https://www.mig-welding.co.uk/forum/threads/no-arc-from-new-power-craft-welder.84399/
I think it applies to your welder. It shows that the circuit board has two functions:
- it switches power on and off to the main welding...
Does this new thread relate to your earlier questions about the JQX-29F relay?
If so, then if you could please respond to the questions I asked six weeks ago:
https://www.mig-welding.co.uk/forum/threads/help-needed.115983/page-2#post-2407686
then this problem could probably be resolved more easily.
From these internal photos earlier:
https://www.mig-welding.co.uk/forum/threads/crypton-triangle-spot-gun-problems.133609/
the failure is in the primary.
As long as you can reach the broken primary wire, and wrap the new solid copper wire "extension", using, for example, 2.5mm2 , to make a good...
Hello and welcome to the Forum !
The TU10 manual suggests that it controls welding current ( contactors ) and gas ( solenoid valve ), and adds HF start ( spark gap and induction transformer ) but does not say anything about adding AC onto a DC-only power source.
In addition, the control cable (...
There is a manual here:
https://www.forneyind.com/site/PDPs/PDPs/Turbo-Welders-Manuals.pdf
but it does not have a schematic diagram.
What information do you need, is your welder not working correctly?
Regarding the "TRIAC Module" : earlier in this thread I was not sure if this component was fitted to your machine. That was before we had the internal pictures. This module is present, it is also known as the Solid-state Relay - SSR, Crydom D2490-10 or Silicon Power Cube 80R2D.
I should have...
There's a lot of undercut. I think you need to reduce the voltage.
To reduce the width of the weld bead, increase travel speed.
Less inductance should help too, try turning the right-hand dial anticlockwise, to the -5 position.
Some notes about inductance:
Having an inductor in the MIG welder...
I doubt if you could find a direct replacement motor and/or wirefeed assembly for this elderly machine.
One of the generic imported all-metal units could be fitted, with some modifications, but they now cost £40 to £50.
Following the suggestions made on your other thread...
Hello and welcome to the Forum.
Regarding the lack of penetration: this may be due to a high-resistance joint somewhere in the high-current secondary path, which will drop the voltage available for welding. Switch off and unplug the machine, remove the covers and check all the joints for loose...
