I have a old esab heliarc 252 which I use mainly as a stick welder, I last used it about 18 months ago and it work fine the only thing with it was that when I turned it on with the main switch on the back of the set the rcd that is fitted to the wall socket tripped out so I reset the rcd and switched the mains on at the wall with the machine already switch on and it work perfectly.I switch it on this week the same way and the machine started up with the fan running and ran for approx: 2 minuets with out any welding and then again tripped out. When it trips out there is a clonk from in side, does any one know about the ESAB, does it have a contactor inside for the motor which may need cleaning and should the fan motor star as soon as it is switch on which it as done since I bought it second hand. It the same machine as the MUREX if any one knows about them.
Reply:I have an old LTec heliarc 250hf. Not sure if it’s a similar machine but I saw a post somewhere regarding cleaning contractors to remedy same problem.
Reply:Yellow case heliarc 252 does not have a large contactor. Weld power is controller by SCRs.Fan runs all the time. Send me your Email address by private message. I might be able to help you some. |
