How To | Reactor Mega

The following information will tell you how to take advantage of the features of the Reactor Mega device.

Change Wattage in TC Mode

While in Ni, SS, Ti, M1, M2, or M3, hold down the menu button and up or down button to increase/decrease wattage then press the firing button.


We can only recommend using the supplied Micro USB cable and wall plug to charge your device. If you are unable to use the wall plug, do not use any third party wall plugs such as a phone or tablet charger or any USB 3.0 or SS ports. Doing so will void the warranty on the device, and may also be a potential safety concern. You can however, use any USB hubs, portable charging devices or computers with standard USB 1.0 & 2.0 ports.

Once connected to a power source, the battery level indicator on the LED screen will flash until fully charged.  Once fully charged, the battery level indicator will stop blinking, shine for 10 seconds and go out. The Reactor Mega battery will take 6.5 hours to obtain a full charge from its fully drained state.
