Cobel TIG AC/DC welder fault

[wheels244]

Hi everybody

I used my Cobel Tig today for only the second time.
It was welding fine on stainless - I then dropped something heavy on the extension lead that it was plugged in to - 100% my fault, whilst the welder was turned on which tripped the MCB on the garage supply.
I repaired the lead and tried welding again and now it won't maintain an arc - it's like its pulsing, but won't maintain a steady arc, and certainly won't start a weld puddle.
I tried on both AC and DC - same results.

What have I done to it?

I took the cover off - nothing obvious - I couldn't see any internal fuses to check.

Can any one shed some light on this please and/or recommend a repairer please.

Thanks

Rob

Thanks Gordon that's great.
I always like to work from recommendation.

I'll give them a ring.

Anybody else got any idea what I've done to it please ?

No I haven't Rik - do you think it would make a difference ?
It was running fine on the extension prior to my mishap.

Thanks

but you said the mishap was on the extension. rules it out. I cant see why a short, which tripped the mcb would cause a problem in the welder, unless there is a fuse or something in the machine has has blown.

Update:

Welder working fine.
I just tried it plugged straight into a socket without extension, works brilliantly.
So, must have been the extension.

Thanks all
