If you bought this from us and the LED does NOT light up when connected – contact us on orders@hawklaser.com and we will send you a new kit.
Factory sent us LED-displays that demands 7.5V to turn on while the output in the K40 is 5V – they are specified to work within 4-30V so we did not notice this when testing after soldering.
We currently do now know which orders has these LED´s installed – if you received one that doesn´t turn on – email us for a new kit or refund!


With the analog K40 lasers the pot to set the power level is very bad, hard to set exact value.

This is a upgrade kit, with a small digital display and a multi-turn potentiometer. This makes it easier to set the power level by higher resolution on every turn.
The display shows a value between 0 and 5.00
Easy for you to remember a value for cutting, turn the potentiometer to that value and go!

The kit is pre-assembled, you only need to replace the old potentiometer with this one.
It´s also possible to upgrade from digital panel to this upgrade instead.
