Hi,
I am off to Adams Gas in Margate in the morning to get a bottle to convert my 151. I have been using it with gasless with cored wire and whilst the welds havent been as tidy as I would like, they are workable. Now I am doing some stuff that people will be able to see so I want to switch to gas.
I know I will need a regulator and I can get that from Adams with the bottle but its how it connects to the 151 I have questions over. There's a white tube at the rear of the unit - does that just clamp on to the output from the regulator? Is it as simple as that? The tubelooks pretty narrow to me. Do I need to get larger tubing from the regulator and some kind of connector to join the 2 together?
Also, what pressure is works best for .8 or 1.0mm mild steel frm the bottle?
Thanks,
RodAndTom

The reg from Adams will probably have a 6mm bore pipe. The one on the rear of the Clarke is probably 4mm bore. You can get an adapter that's like a quick release fitting to connect the two but I've yet to find one that's gastight. I got fed up of mine recently. i found a piece of windscreen washer tube was a good fit over the 4mm pipe and inside the 6mm pipe so I cut a length around 3 inches long, slid it over the plastic pipe on the welder and then pushed the rubber pipe from the reg over it. I used a jubilee clip at each end of the resulting 3 layer sandwich and it's gastight. I use PCL fittings in the rubber pipe to allow me to disconnect the welder from the bottle.
I always turn the gas off at the bottle when I'm done anyway and then I pull the trigger on the welding torch to release the gas (welder switched off). I recently forgot the last step and when I pulled the trigger of the welder a day later I got a hiss of gas as the pressure in the line was released - I'm surprised the valve in the welder held the pressure that long to be honest as they aren't usually that great (nor do they need to be) but it certainly proved my joint.

Hi,
Adams were very helpful.I've got a 9L bottle of CO2 with 5% Argon for a 1 off payment of £91 (includes £55 deposit on the bottle) with £30 refills I believe. Then I got the regulator for £25+vat. I've bought the joining tube from Machine Mart so I am all ready to go. I shall try it this evening and look forward to superbly smooth welds
