Why Does My 1.6A 110V Multi Tool Surge On With Router Speed Controller?

I have an AC powered multi tool cutter (power tool) It is 1.6 amps 110V

I want to be able to control the speed and run it very slow, so I connected it to an AC 110v router speed controller that is rated at 15amps. The tool plugs into the speed controller unit and the unit plugs into a 110v wall outlet.

The peoblem is that when I rotate the knob to contol the multi tool speed, it won't turn on until the speed controller knob is turned 1/3 the way up. Then the tools jumps to life and then I can turn the speed controller knob all the way down and it runs there. Why do I have to turn it up to 1/3 of the way to get it to start, and why does it surge on? I did try plugging in an additional speed controller into the mix and this worked better to start the multi tool at a lower speed without the jump. It 'seems that the second speed controller caused more 'resistance'? therefore making the multi tool work better at a lower speed? ?  What can I do to make the speed controller work flawlessly at the lowest setting? Is there anything I can buy off the shelf so to speak to solve this problem?

Thank you,

Are you aware of the things you are plugging into? You have a tool cutter rated 1.6amps 110volts, then you connect a speed controller with 110v but is rated 15 amps which is ok. But the thing is, it is rated 15amps so somewhere out there when you turn the knob of the controller, it is only at 1/3 of the way does it supply current enough to power your tool cutter. I would suggest use a regulator to power the tool cutter.

Hi Kevin,

Thank you for your reply,

I am not skilled or knowledgeable with electrical matters and how they work.

I did some research today after I posted this question and found using an online
converter- that at 110V and 1.6Amp motor rated - that the conversion to watts is
at 176 watts. The speed controller I used was 110V 15A so the conversion is 600 Watts.
This might be the problem with it being jumpy and at a 1/3 turn of the speed controller to start it?

I found another router/fan speed controller rated at 200 Watts or an equivalent of 1.8 amps, so closer to the actual amps of the motor. Do you think this might work? Or do I need to go higher on the watts to get it to start as soon as I start to turn the knob?

Also, thank you for the recommendation- Please explain how I could use a regulator to make this work better, and is this something I can buy easily off of say E-bay or Amazon?

Thank you for your time,

Paul
