Hi Ola, I like to use a true variac.

I have 3 and bought all for very reasonable prices.

I use them exclusively on the Jensen 50.

Like these.  0-130 volts 20 Amp

If your mains are 220 volts, you ought to be able to find something reasonable.

I have had success with a simple room light dimmer for control of the Jensens 600 watts or under.

Even with lower wattage requirement engines I prefer having a meter and clearly marked dial.

I did try one cheap one that was impossible to get a good handle on the output. 
It's gauge was never true and rarely off in the same direction and amount.
I  other words, all over the map. I was better off with my simple light dimmer with no meter.
