Hey Tony,
We call them weed burners out here. Back East in the snow country they use them to melt snow and ice with. All it is, is a propane tank with a big torch attachment. A lot of roofers use them out here for laying hot roofs. Just fire the thing up and apply heat to the strips and it melts off. Nothing to it. Hope this helps.
