Tips and Recommendations

Updating the firmware of the HS-02 to version 1.7 allows users to disable the rolling temperature animation feature.
When choosing between C245 (HS-02A) and C210 (HS-02B) tips:
- C245 is suitable for general-purpose work with cartridges down to 0.3mm, enabling fine work.
- C210 heats faster due to lower mass, but smaller geometry and tip may make larger work more challenging.
For intricate tasks requiring tips smaller than 0.3mm wide, cheaper USB soldering irons may not suffice.
