Weller WESD51 Knob.
This is a 3D printed replacement knob for the Weller WESD51. This is a slip in replacement. For permanent install melt the back side of exposed plastic so it cannot be removed.
Instructions:
Removing the old knob. Remove feet off unit. Remove 4 screws. Take off blue cover. Remove 1 screw off back of the current knob. Pull knob out or broken part out. Carefully insert new knob (feel for the slotted insert. Do not force it in) Melt the exposed black plastic of new knob for a permanent solution if you don't require permanent than do not melt. You don’t need that old screw from the old one. Put unit back together and you’re all set.
If your unit is locked into a temperature then place a magnet on the bottom right of the front of display to unlock temperature.
I do throw in 1 extra just in case it fails.
FYI I offer custom colors as well so if you want a custom color than black just message me after the purchase with the color you want and I will see if I have it available.
