Tig torch conversion?

Simple enough to just add switches to a standard TIG torch handle, but in Europe many torches are available with trigger buttons. Binzel probably makes an optional handle tube for your torch with the trigger buttons built in.

I added a trigger button to the torch I use on my Inverter. I just bought a replacement trigger switch as used in many plasma cutter handles.

it is probably simpler to just make an adapter cable. All it takes is the right plugs and an ohmmeter to figure out where the switches are connected on the two torches.

Thnx for tht Ernie............the torch i have does have a simple on /off switch already, but i am not overly concerned about the switching arrangements, as I would like my watercooled torch to be as light and compact as possible, with foot pedal only control.

Just wondered about changing the socket on the front of the machine to accept watercooled torch, and whether anyone had any bright ideas, regarding how i might retain trigger torch functions if needed (not really enough room for a separate socket for each torch).

thnx

Here's a link to a diagram Ernie posted a while back. It helped me out:

Thnx John ............just what I was looking for, very helpful! Everyone have a good xmas a prosperous new year!

Hi Chris,We have converted a number of 200 amp Inverters to watercooled Torches but it needs some modification to the machine.With a gas cooled torch the argon goes through a solenoid valve and is fed to the centre of the current connector and travels through the centre of a Bicox assembly to the torch head.With a watercooled torch the passage down the centre of the torch carries the returning water going to the watercooler.Without that internal cooling water the torch would soon burn out.We have to fit a separate argon outlet on the front of the machine and use the original power/gas connector to take the water return back to the watercooler.The water in pipe on the torch is fitted direct to the water supply from the cooler. Should you have a 2 piece gascooled torch ie.separate gas hose & power cable connected to a Dix type power connector,then it should be possible to make the connections to water & gas outside the set but you would not have the facility of a gas solenoid valve. Hope this helps,but the description make more sense with the machine in front of you.It also depends on the free space inside the Inverter.

Thnx for that Gwyn...........it looks as though I will be able to sort something out along similiar lines to what you have described. I should be able to dismantle the watercooled torch I have, and fit connector block from original gas cooled torch, connected to argon feed and power, of watercooled, and then connect water feed and return lines, by using quickfit couplings, to return and feed of watercooler unit.

Basically a mix and match sort of conversion, but which will leave front of machine totally stock, meaning it would be very easy to reconnect gas cooled torch, should I wish to use program features, controlled by torch trigger switches. Anyway many thnx for everyones help on this posting, and hoping you all have a good Xmas and a prosperous new year!
