Re: [RE-wrenches] poly pipe welding/fusing machines

Hi Jay, I picked up a used McElroy 2LC butt welding set-up on Ebay for $600 a few years ago and I love it. It has jaw insert adapters for different size pipe and can work with 1/2" up to 2". Mine is an older version of this brand new one on Ebay now:
