T-962A Reflow Solder Oven
This solder oven from China is cheap and sturdy. It has a bunch of technical issues that are quite easy to fix, thanks to Unified Engineering, a Swedish organisation that has made an alternative firmware available for free.
Step 1: Grounding Wire
Remove the grounding ring, then completely remove the paint that keeps the grounding pin from touching the metal, the reattach the ring. Even better, puchase two ground terminals and connect a second wire to the lid.
Step 2: Replace Masking Tape
Remove all masking tape on the heat protection. Don't forget to remove the tape in the front under the heat shield. Replace with multiple layers of Kapton tape or other non-conductive heat resitant material.
Step 3: Reflash the Firmware
Step 4: Solder in the Temperature Sensor
