cebora 130

[jontoghill]

Hello everyone, i`ve been checking out the forum for a little while as i had my welder stolen and was wondering what to replace it with. I bought another cebora 130, it seems like quite a good little welder and i only do my own repairs/projects. But i bought it from ebay and as i expected it`s come with problems. One was the gas not coming through which i`ve put down to a worn/damaged o-ring in the on/off tap. The other i think is a bit more serious, there`s no ark. The motor and wire feed work and the line feed to the gun seems to have been replaced. On the circuit board i found blackening around the resistor(3.3ohms/7w) so i`ve bought a replacement from maplin but the rating is 3.3ohms/10w, it`s also physically larger but they said that the difference wouldn`t matter, is this right?. Can anyone tell me what could have caused the resistor to blow(if it has), how much it`s likely to cost please. I do have limited electrical knowledge so please keep any replies simple, my brain tends to shrivel if things sound too technical.


Thanks Jon

Hi Jon,
No worries replacing a 7W resistor with the equivalent 10W one as long as it will fit in OK without being crammed up against other components. As far as what caused it to fail in the first place - I'm afraid I'm clueless on that - sorry. Maybe someone who is familiar with the innards of the machine will come along in a while? Do you not have any comeback on the ebay seller?
Good Luck,
Graham.

Thanks Graham, i`ll go ahead and fit the new resistor and see what happens. I bought the welder as spares or repair so really, i paid my money and made my choice. I did ask whether the motor worked and whether the gas came through when the trigger was pulled. His reason for selling was that he`d bought it 6months ago and hadn`t used it which is why he listed it as spares or repair; who knows. It stands me in at 90 quid so far including getting hold of it, so if i can get it working without spending to much more on it i`ll be happy.
