When you're removing red-hot steel for quenching, you need the superheated door out of your way, not in your path. The side-swing design positions the door safely away from your body and workspace, and the cool-touch handle at the front makes one-handed operation simple even with tongs in your other hand.\u003c\/span\u003e\n\u003c\/div\u003e\n  \u003cdiv class=\"d-faq-item\"\u003e\n\u003cspan class=\"d-q\"\u003eIs the Quiet Drive Solid State Relay worth the upgrade for heat treating?\u003c\/span\u003e\u003cspan class=\"d-a\"\u003eAbsolutely. Evenheat's patented Quiet Drive relay fires up to 60 times per second versus 10 times per second for standard mechanical relays, delivering exceptionally tight temperature control. For heat treating where precise temperature management directly affects blade hardness and performance, this upgrade provides consistency you can measure in your finished work. It also eliminates the clicking noise of mechanical relays.\u003c\/span\u003e\n\u003c\/div\u003e\n  \u003cdiv class=\"d-faq-item\"\u003e\n\u003cspan class=\"d-q\"\u003eDoes buying from Peach State Pottery affect my warranty?\u003c\/span\u003e\u003cspan class=\"d-a\"\u003eNo. We are an authorized Evenheat dealer.
