darren 67 Posted June 23, 2013 Report Share Posted June 23, 2013 Silly question but have you turned gas on and pressure up on gauge? Quote Link to comment Share on other sites More sharing options...
Lord Geordie Posted June 23, 2013 Report Share Posted June 23, 2013 Is the gas bottle full? The regulator may not be working or failing that the valve in the grip! Quote Link to comment Share on other sites More sharing options...
Whytie2697 Posted June 23, 2013 Author Report Share Posted June 23, 2013 I have a full bottle I took the pipe off the regulator and the gas comes out I the regulator then I took the pipe of the push in fitting at the welder end no gas getting as far as that so the problem must be with the coupling that goes into the regulator and the hose connects over the top of Quote Link to comment Share on other sites More sharing options...
Tam Posted June 23, 2013 Report Share Posted June 23, 2013 Does your "no gas mig" have a gas torch ? Quote Link to comment Share on other sites More sharing options...
Whytie2697 Posted June 23, 2013 Author Report Share Posted June 23, 2013 Good question how would I know that it just says in the booklet to switch the polarity and then connect up the bottle Good question how would I know that it just says in the booklet to switch the polarity and then connect up the bottle Quote Link to comment Share on other sites More sharing options...
Tam Posted June 23, 2013 Report Share Posted June 23, 2013 Take the torch connection off & see if it has a port for Gas as well as wire Quote Link to comment Share on other sites More sharing options...
Whytie2697 Posted June 23, 2013 Author Report Share Posted June 23, 2013 Yeah it has like a few ports around the nozzle where the wire comes out the welder has like a small hose that the hose from the bottle goes into then it disappears into the welder I assume it links up with the hose for the torch somewhere I can't see but the gas is not even getting as far as this small hose Quote Link to comment Share on other sites More sharing options...
hcarlos Posted June 23, 2013 Report Share Posted June 23, 2013 Does the regulator have a dial to turn flow up this maybe on zero??? Quote Link to comment Share on other sites More sharing options...
Whytie2697 Posted June 23, 2013 Author Report Share Posted June 23, 2013 Yeah it has a dial it was on about 20 cfn but I tried it up as high as 40 still nothing comes out of the end if the hose where it couples to the welder Quote Link to comment Share on other sites More sharing options...
Potter64 Posted June 23, 2013 Report Share Posted June 23, 2013 Did you make the pipe up yourself, you haven't used one with a check valve have you as these only flow one direction Quote Link to comment Share on other sites More sharing options...
Whytie2697 Posted June 23, 2013 Author Report Share Posted June 23, 2013 Yeah spot on that is what the guy sold me in the shop on receipt it says 3/8 check valve what do I need to replace this with it how will I know that it is allowing the gas to flow the correct way when I get a cm chance to replace it as this one must only allow gas to flow back to the bottle not from the bottle to the welder Quote Link to comment Share on other sites More sharing options...
hcarlos Posted June 23, 2013 Report Share Posted June 23, 2013 Can't you turn it round so it allows gas to flow to the welder but not back to the bottle Quote Link to comment Share on other sites More sharing options...
welsh1 Posted June 23, 2013 Report Share Posted June 23, 2013 Is your tip clear,if its blocked then the check vale will stop gas flow Quote Link to comment Share on other sites More sharing options...
Whytie2697 Posted June 24, 2013 Author Report Share Posted June 24, 2013 The tip is clear but I can't turn it around as one end is threaded and screws to the regulator and the other end is tapered for going into the hose Quote Link to comment Share on other sites More sharing options...

Tiger955i Posted June 24, 2013 Report Share Posted June 24, 2013 Hi Mate I had a Clarke gas/no gas mig and had what sounds like the same problem as you have I disconnected the gas supply and unplugged the welder then I looked instde Inside the torch where the gas release was controlled by the trigger. The design was fiarly simple, the feed tube was a soft rubbery material which was simply squashed flat when you released the trigger. I found that the flattened tube stuck to its self so remained shut off. It was fairly easy to free the tube where it had stuck to its-self and never had a problem after that. I hope that is of some help. J. Quote Link to comment Share on other sites More sharing options...
Whytie2697 Posted June 24, 2013 Author Report Share Posted June 24, 2013 Thanks for the replies my problem is that the gas is not getting as far as the torch when I disconnect the hose where it joins the welder there is no gas coming through when I turn the bottle on I think it is because I have a check valve like someone said previously what I need to know now is what I need to replace the check valve with it connects into the regulator and then the hose clamps onto the other end Quote Link to comment Share on other sites More sharing options...
Potter64 Posted June 24, 2013 Report Share Posted June 24, 2013 You just need a standard 3/8 connector with a tapered tail all you need to do is blow from the nut end to make sure it's ok or tell the bloke in shop it's for the regulator end he should then know Quote Link to comment Share on other sites More sharing options...
Whytie2697 Posted June 24, 2013 Author Report Share Posted June 24, 2013 Right ok thanks very much for all help especially potter64 he has solved the problem I think the guy In the shop wasn't the welding guy so he just asked me would I know what the coupling looked like so I went with him and picked out the right size I didn't know they was standard or a one way valve if I get a standard one will I still have to blow through it to check Quote Link to comment Share on other sites More sharing options...

Potter64 Posted June 24, 2013 Report Share Posted June 24, 2013 No yours will have a bit behind the nut about 20 mm long this is the check valve it's usually used connected to a cutting torch it acts like a flash back arrestor to stop flame traveling up the pipes You don't need this the one you want will just be a nut and tail in 3/8 the tails do come in different sizes depending on the pipe your using so just take the pipe with you Quote Link to comment Share on other sites More sharing options...
