## MHP30 60W preheater hotplate

The MHP30 60W preheater hotplate is a great soldering and reworking tool for your electronics projects.

See post #867 also.

This tool sells for about $75 and $100 USD (without and with power supply); at first glance it seems like a small expensive toy.

In fact, the hotplate can be particularly useful on your work bench.

By itself, the MHP30 can be used to solder and unsolder SMD parts in under 15 seconds.

The hotplate surface is 30 mm X 30 mm which has a ceramic coating over a brass element.

You can set the temperature using the OLED panel from 100° - 350°C, has 3 preset temperatures.

For high mass components like inductors and TO220 cases, 350°C is more than enough heat.

I usually use the M1 temperature setting which is ~220°C @3%.

Unit offers power wake-up and automatic sleep.

The OLED menu is navigated by two back mounted A/B switches.

There will be 4 more posts after this, discussing DIY addons to extend the use of this tool.
