Apparatus and methods for positioning one or more components relative to a work surface are provided. The apparatus can include a frame having a first support member extending therefrom. At least one extendable member can be disposed on the first support member. The extendable member can be adapted to move in a linear direction. At least one magnet can be disposed on the frame. The magnet can include at least one contact side that can be switchable between a magnetized state and a non-magnetized state.

What is claimed is: 1. A portable welding tool comprising: a frame having at least two vertical support members and at least one horizontal support member; an extendable member disposed on the horizontal support member, wherein the extendable member is adapted to move in a linear direction between the vertical support members; at least two switchable magnets each disposed on one of the vertical support members, wherein each switchable magnet includes a contact surface that is switchable between a magnetized state and a non-magnetized state, and wherein each magnet comprises a housing, at least two permanent magnets, and a lever for causing relative rotation of the permanent magnets; and at least two wheels disposed on the frame, apart from the magnet. 2. The apparatus of claim 1, wherein the extendable member is adapted to move in a linear direction between the magnets. 3. The apparatus of claim 1, wherein the horizontal support member is vertically adjustable about the vertical support members. 4. The apparatus of claim 1, wherein the extendable member is mechanically, hydraulically, or pneumatically actuated to move relative to the horizontal support member. 5. The apparatus of claim 1, further comprising a handle disposed on the frame to move or position the apparatus. 6. The apparatus of claim 1, wherein the magnets are rotatably disposed about the vertical support members. 7. A method for welding comprising: positioning a portable welding tool on or adjacent to a work surface to be welded, the tool comprising: a frame having at least two vertical support members and a least one horizontal support member; an extendable member disposed on the horizontal support member, wherein the extendable member is adapted to move in a linear direction between the vertical support members; at least two switchable magnets each disposed on one of the vertical support members, wherein each switchable magnet includes a contact surface that is switchable between a magnetized state and a non-magnetized state; wherein each magnet comprises a housing, at least two permanent magnets, and a lever for causing relative rotation of the permanent magnets; and at least two wheels disposed on the frame, apart from the magnet; and welding the work surface. 8. The method of claim 7, further comprising actuating each magnet to the magnetized state. 9. The method of claim 8, further comprising extending the extendable member to engage against the work surface. 10. The method of claim 9, further comprising releasing the tool from the work surface by switching the one or more magnets in the magnetized state to the non-magnetized state. 11. A portable welding tool comprising: a frame having a first support member extending therefrom; at least one extendable member disposed on the first support member, wherein the extendable member is adapted to move in a linear direction; at least one magnet rotatably disposed about the frame, wherein the magnet has at least one contact side that is switchable between a magnetized state and a non-magnetized state; and wherein the magnet comprises a housing, at least two permanent magnets, and a lever for causing relative rotation of the permanent magnets. 12. The apparatus of claim 11, further comprising a second support member that extends from the magnet, wherein a side of the second support member includes a contact point that is planar with the contact side of the switchable magnet. 13. The apparatus of claim 12, wherein the second support member extends in an opposing direction from the frame as the first support member. 14. The apparatus of claim 12, wherein the second support member includes one or more gussets for reinforcing the second support member. 15. The apparatus of claim 11, wherein the first support member is substantially parallel to the contact side of the magnet, and wherein the first support member is linearly adjustable relative to the contact side. 16. The apparatus of claim 11, further comprising at least one wheel disposed on the frame, apart from the magnet. 17. The apparatus of claim 11, wherein a contact surface of the extendable member is substantially parallel to the contact side of the magnet. 18. The apparatus of claim 11, further comprising one or more counterweights disposed about the frame to provide a counterbalance to the extendable member, the first support member, or both. 19. The apparatus of claim 11, wherein the extendable member is mechanically, hydraulically, or pneumatically actuated to move relative to the first support member. 20. The apparatus of claim 11, further comprising a rotatable connection disposed between the magnet and the frame, wherein the rotatable connection permits at least partial horizontal rotation of the magnet relative to the frame.
