220817 shields appear to be in stock at Hypertherm.....we have a same day shipping policy if orders from our distributors are called in by 3 PM eastern time. If your distributor ordered them for you from Hypertherm....they should have arrived in a couple of days. I would double check with your distributor...likely the order was not placed yet.
If you go to the Hypertherm | Plasma Cutters | Plasma Cutting Equipment | Metal Cutting Equipment site and click on "where to buy" you can locate the local distributors....these parts should be in stock at many locations.
Please contact me directly if you cannot resolve this issue...and I will get our local Rep to make some calls for you. email@example.com
