Abstract: |
|||
| The present invention concerns a method of direct resistance heating of the metal parts and digital display of heating temp. through the resistance temp. coefficient. The equipment is an electric heating car comprising an internal combustion engine driven generator, an auto-transformer, the temp. measurement and control system based on a single plug-in board computer, lead cables and electrodes. It heat-treats the workpieces, and is useful for the field work. | |||
