So, Which Do I Choose?

The best choice of machine will be mostly dependent upon your needs as a contractor. If you are following work that is mostly done outside or commonly on sites that have no power supply, then propane is a great choice.

Other project types such as asbestos abatement and projects where obtaining single phase power is difficult, then propane is also a great choice. On projects where power is plentiful and easy to access, then electrical is a good choice and the machine requires almost no maintenance.
