A handheld welder is provided for welding together parts of a workpiece. The welder may include a pair of three-part clamps with spring-loading so as to temporarily hold the parts of the workpiece in place before tightening the clamps. A housing can be provided for housing batteries or at least part of a power cord and for structurally supporting a heater element during welding. The housing can include radially-extending screws that are slidably provided within slots of a sleeve to allow the housing to axially move within the sleeve, so that the heater element may be at least partially retracted into the sleeve once the welding operation is completed. |
