Abstract
Some examples of the present disclosure relate to welding torches having a thermal insulating plate (). The thermal insulating plate is comprised of a thermally insulating material, and is positioned between a front housing () and a drive gearbox () of the welding torch. The front housing () is connected to a gooseneck that conducts electrical energy to a torch tip (i.e. front end) of the welding torch. The drive gearbox () includes a gear assembly configured to drive a drive roll that moves a wire electrode through the welding torch (e.g. toward the torch tip of the torch). The thermal insulating plate () acts as a heat dam to decrease and/or reduce thermal energy transfer from the torch tip of the welding torch (e.g. via the front housing) towards the rear of the welding torch (e.g. through the drive gearbox), where the thermal energy may heat the welding torch handle and/or damage some of the more expensive and/or sensitive components in the handle (e.g. a motor of the drive gearbox).
