I am sure they are expensive but in a very old house like i was in the smallest spark can set a house on fire. And yes i always have a fire extringuisher and water at arms length away

This is copied from a post I made a couple of days ago. See the red letters below. I can take a photo and post it if you wish.
That was a NIBCO LETROSWET ... High and low power settings and off / on switch. Over the years it has opened hundreds of frozen pipes. The other feature was a electric torch up to 3" capacity. The carbon contacts heated up a 3" copper joint in about a minute and a half. This thing still works and has to be in this shop for at least 40 years. The only maintenance was the replacing of the copper lugs on the clamps. This had to be done after every 50 thaws.
