That is *certainly* a way to create life-threatening situations! A somewhat acceptable way to create a 240V circuit using two independent 120V branches is to use single pole relays that pull in after you plugged in the socket and an additional 240V relay that drops out as soon as one of the two plugs is removed. Each 120V relay is powered from one 120V plug and its NO contact makes contact between incoming AC and one of the outgoing phases but one of the outgoing wires is also interrupted by the NO contact of a 240V relay that will drop out as soon as one of the incoming 120V plugs is pulled, so the load does not continue to hold one 120V relay with the 120V from the other leg. NOTE that the 240V relay must have a lower current rating than the min hold current of the 120V relays.
No doubt there are other circuits to protect this kludge, but it is best to simply use a 240V outlet!

Now you have 220.
