I've never used a HF welder, so I can't recommend that... pullers are soemthing to stay away from, unless you have fab skills and can make new mandrel arms for them.

EDIT: Typed this in the hurry - by mandrel arms, I'm referring to the plates that go from the middle of the puller to hold the actual arms. Plates with a hole in each end, bolt goes through them, there are two per "finger" of the puller.
