Mig welder problem

[scaff]

Earlier today I was welding on a new sill to my Mini Cooper. 

I got it on, all welding done. Then decided to fit one more patch to the inner wing. 

Then it all stopped working. 

I press the trigger on the torch, the welder sorta buzzez but no wire comes out. 

I can hear the fans running on the welder and the power light us on, but no wire.

It's a mightymig 150

New 0.8m in it today

the overload light never came on during use


any ideas?



thanks

How olds the torch ? The liner may be fecked . Either that or theres no tension on the rollers or the motors shafted . I think iots the wire stuck in the torch though .

I've slackened off the tension on the wire roll.......no good

Then removed the tensioner on the wire feed......no good

I can pull the wire through with pliers......so liner ok

The welder is a little over 12mths old ...... No warranty

Found the problem.

I had some time free before the rugby today so I thought..........welder

Opened it up and one if the thick alloy cables to the transformer had snapped at the bolt head that secured it




A quick unbolt, strip off reform rebolt up and it's wire feeding happily


Phew.



Thanks all
