AGA Norgas E100 -5 Tig

[KEB]

Hi folks,

I have a welder as above, this appears to be the same as one in a post from many years ago and is the top two images.
Mine is different (bottom two images) where as the amp dial has been replaced by a series of bayonet sockets of which the plug fits into, not ideal but it works.

The problem I have is that the argon gas continues to come through after I release the thumb button on the torch, previously it cut off after a short delay.

I have the cover off at the moment (another 2 pics?), and am looking in the casing for a solenoid or something that would be the likely culprit in not cutting the gas off when needed.
The bottom image shows the machine on its side, and in the botton right of the pic is what i think is the switch/ solonoid (light green) that regulates the gas to flow or to cut off? the gas entry point is the pipe that connects to it.

Anyone have any ideas? certainly would be appreciated.
Thank you.

Just follow the gas pipe, who was it in 2006 said he might have a manual ?
Don't worry Uncle joe will be along soon

Hello there,
Thanks for your post.
No, have not changed name as this is my first introduction to the forum.
I was searching the web, then came across the 2006 discussion that you mentioned, thus thought it wise to suscribe.

Have since applied a (very) light tap to the green (assumed) solonoid. now the gas cuts off after releasing the torch button, albeit a bit intermitently - and on occassions the gas keeps on flowing.
but nevertheless it is some form of progress.

Could not see the reference to a manual anywhere though.
Thanks again.
