From the looks of it, OP is confused of lightning and he thought that mainnet and lightning funds can be sent though either network.
what if you send the bitcoin to a legacy wallet non wetsig/lightning will you loose the bitcoin or can the transaction be cancled
Let's say that you already have an open channel and you go to the send tab:
If you paste a
Bitcoin address there, Electrum will send a normal transaction and spend your on-chain funds.
If you paste a
lightning payment invoice there, Electrum will initialize a lightning payment.
It depends on what you've pasted; bitcoin addresses, on-chain payment invoice (
eg. from payment processors) and lightning invoice (
long string that should start with 'ln') are very very different from each other, you do not have to worry about losing funds.
And read Abdussamad's reply.
P.S.: it's "
SegWit" not "
WetSig" (
sounds kinky)
