Abstract
A spool gun having a very unique look, due to its arrangement of features. The spool gun has its wire spool compartment located below the handle and the user's hand, when the user is gripping the spool gun in an operational position. Operably connected to the wire spool compartment is wire spool brake configured to engage with the wire wraps. The brake can have a lock and/or a wire spool life indicator. The wire spool compartment has a cover that is non-threadedly engaged. The feed rate of the wire from the wire spool compartment can be adjusted by a control device, such as a knob, located proximate the user's hand, when the user is gripping the spool gun in the operational position.
Claims20
A spool gun having a distal end configured to be positioned away from the user when the spool gun is in use and a proximal end configured to be positioned proximate the user when the spool gun is in use, the spool gun comprising:
- a body portion;
- a wire feed subsystem comprising a drive motor and a wire feed mechanism;
- a handle portion having a first end connected proximal to the body portion;
- a wire spool housing having an interior with a center point and a removable cover providing access to the interior;
- and
- a spool brake comprising a pressure plate with a face located within the interior of the spool housing and a compression spring configured to bias the face of the pressure plate toward the center point of the spool housing, the face of the pressure plate and the compression spring axially aligned.
The spool gun of claim, 1, wherein the handle portion has the first end connected proximal to the body portion and the handle portion has a second end that extends toward the proximal end of the spool gun.
A spool gun having a distal end configured to be positioned away from the user when the spool gun is in use and a proximal end configured to be positioned proximate the user when the spool gun is in use, the spool gun comprising:
- a body portion;
- a wire feed subsystem comprising a drive motor and a wire feed mechanism;
- a handle portion having a first end connected proximal to the body portion;
- a wire spool housing having an interior and a removable cover providing access to the interior;
- and
- a spool brake comprising an elongate arm with a pressure plate at a first end of the arm, the pressure plate having a concave face, and a compression spring axially aligned with the arm at a second end of the arm, the pressure plate located within the interior of the spool housing and the compression spring located external to the spool housing.
A spool gun having a distal end configured to be positioned away from the user when the spool gun is in use and a proximal end configured to be positioned proximate the user when the spool gun is in use, the spool gun comprising:
- a body portion;
- a wire feed subsystem comprising a drive motor and a wire feed mechanism;
- a handle portion having a first end connected proximal to the body portion and a second end;
- a wire spool housing connected to the second end of the handle portion and having an interior and a removable cover providing access to the interior;
- a hollow armature extending from the wire spool housing to the body portion;
- and
- a spool brake comprising an elongate arm with a pressure plate at a first end and a compression spring axially aligned with the arm at a second end, the arm and compression spring located within the armature and the pressure plate located within the interior of the spool housing.
