thermal dynamics 1torch is a very good retro fit if you can get one for your machine i would contact thair tec dept direct to get part no. and would prob have to buy from one of thair local suppliers if you cant buy direct.
retro fit will be alot more expensive than finding compatable spares!
i used to work at proweld at plymouth
http://www.proweld.co.uk/ say barry said you should be able to help and thay will sell via mail order you need to speek to someone in the workshop to get rigt part no. and adrian in store/tel sales is very good for any welding spares but dont forget to ask for a good price
