Abstract
An example system includes: a hand-held welding tool that is manually placed in a welding position, wherein the hand-held welding tool is configured to be activated to cause a contact tip or a welding heat source to automatically move from a first position and to second position during a welding operation, and wherein a welding arc is automatically and repeatedly turned off and on while the contact tip or the welding heat source moves from the first position to the second position to make a plurality of welds between the first position and the second position, wherein, as a travel speed decreases, a time period between each arc on time increases to make equally spaced welds.
Claims17
A system, comprising:
- a hand-held welding tool that is manually placed in a welding position,
- wherein the hand-held welding tool is configured to be activated to cause a contact tip or a welding heat source to automatically move from a first position and to second position during a welding operation, and
- wherein a welding arc is automatically and repeatedly turned off and on while the contact tip or the welding heat source moves from the first position to the second position to make a plurality of welds between the first position and the second position,
- wherein, as a travel speed decreases, a time period between each arc on time increases to make equally spaced welds.
A method, comprising:
- manually positioning a hand-held welding tool to engage a workpiece;
- starting a welding operation from an initial position based on a first event;
- automatically moving a contact tip or a welding heat source from a first position to a second position relative to the workpiece during the welding operation;
- and
- repeatedly and automatically turning a weld current on and off while the contact tip or the welding heat source moves from the first position to the second position to make a plurality of welds between the first position and the second position;
- and
- controlling a time duration between successive weld current on times to make the plurality of welds.
A hand-held welding tool that is manually placed in a welding position for set of multiple welds, comprising:
- a motion device configured to automatically move a contact tip or a welding heat source during a welding operation;
- at least one of 1) a bracket or 2) a sensor with a trigger lock, configured to ensure a work angle between at least one of the contact tip or the welding heat source with respect to a joint being welded;
- and
- a triggering device configured to cause the motion device to automatically move the contact tip or the welding heat source from a first position and to second position during the welding operation,
- wherein a welding arc is automatically and repeatedly turned off and on while the contact tip or the welding heat source moves from the first position to the second position to make a plurality of welds between the first position and the second position,
- wherein, as a travel speed decreases, a time period between each arc on time increases to make equally spaced welds.
