Hello,I am having a problem with my welder it is a Hobart TR 250 HF.I bought it new about 25 years ago and it has served well.I have never used it much on the HF side,because most every thing I do is stick.Now the problem,just tried to use it today and it would barely strike an arc turned it up same thing only a little better but still not good enough to weld anything.Got out my meter and checked power coming in 240 volts good.Took apart the leads and checked continuity all was good,put everything together still the same.Is there any one here that could give me an idea where to go next?Thanks 50cal
