I need some help. Last July I bought a like-new PCM 500i from a Ricmond, VA pawn shop. It had a blue factory shield, original swirl ring and unknown tip, presumably OEM. The unit looks like it was rarely used. It had no extra consumables with it but performed as well as could be expected for an absolute newbie using it. I couldn't find consumables locally so ordered some off the web. First batch did not work as the nozzle was too deep to allow the electrode to activate the plunger and initiate air and current. Bad item is on the right below. Left nozzle works....kind of.
Anyway, the factory blue shield gave out at the business end and lost ceramic and would no longer hold the nozzle in. Swirl ring was also damaged.
So, I switched to all Chinese consumables, including swirl ring. See the condition of the nozzles below and other pictures in the next posting.
This is a standoff mechanism I fabricated from plastic rod mount and TIG tungstens because it seemed to help early on. I've not been able to find a drag nozzle or standoff attachment for this torch.
