Hi all,

22, from London, like to tinker about with bikes. I've had no formal education on how to weld, only been taught by my friend who was taught in the garage where he works. But whatever I do it seem ok (strong and not ugly). I can tell and gauge what a good weld is and what I need to do it, i.e. control power, control wire feed etc. I would love to have some forma education and really know about metal work. May do an evening course one day who knows!

Ive got a Cebora 130 pocket mig, had it about a year, used it a fair bit, it does me fine. The other day i turned it on and the gas just kept flowing. Even when the power is off (by the mains) and i turn the gas on I can hear it still flowing. A bit of research said it could be the solenoid valve? This is a much as I know! Not very knowledgeable about the insides of a welder. Any clues?

Thanks all!

Mackenzie

sounds like its stuck in open don't it just. Swap it out or get someone to do it for you

Do you know where it is? Ive had it open and cant seem to find where it is?

Pretty sure that the gas valve on the pocket mig is in the torch and is manually opened when you pull the trigger on the torch, probably an O ring or seal has failed, or if you are lucky its just the button stuck in, it may be repairable or just buy a new torch neck for it. example here http://www.weldequip.com/cebora-gas-valve.htm

Your machine will have either an electrical solenoid or a valve in the torch.

If it uses a solenoid it'll be inside the welder and easy to find, just follow the gas pipe into the welder and it's a little box with two wires going to it. Make sure the welder is unplugged before taking covers off though.

If it's in the torch you need to unscrew the torch and it'll be a fairly simple valve moved by the torch trigger.
