Abstract

A tool less method of connecting a welding-type power source with a cart is disclosed. In some examples, the cart may be configured to carry one or more gas bottles (and/or cylinders). In some examples, the power source housing and the cart may connect at interfacing ends and/or walls of the housing and cart. A connector, such as a clip for example, may span the interface to connect the power source housing and the cart. Catches (e.g. slots, holes, crevices, and/or protrusions) may be formed in and/or on the power supply housing and/or cart proximate to the interfacing ends and/or walls. In some examples, the catches may be aligned. In some examples, the cart and/or power source housing may include alignment surfaces to assist with alignment. The connector may engage the aligned catches to connect the welding-type power source and cart together at the interface.

First claim

What is claimed is:

1. A system, comprising:
a welding-type power supply having welding-type circuitry and a housing enclosing the welding-type circuitry, wherein the housing comprises first and second sidewalls connected by a floor, a first end wall, and a second end wall, the housing further comprising a first upper clip catch and a first alignment surface, the first alignment surface comprising a protrusion extending from the floor;
a cart having a base, wherein the welding-type power supply is positioned on the base, wherein the base comprises a first lower clip catch and a second alignment surface, the second alignment surface comprising a hollow depression in the base of the cart, wherein the protrusion of the housing is configured to fit in the hollow depression of the cart to align the first upper clip catch with the first lower clip catch; and
a first clip attached to the welding-type power supply or cart via a spring loaded pin, the first clip being movable between a securing position, where the first clip secures the power supply to the cart via engagement of the first upper clip catch and the first lower clip catch, and a released position, where the first clip does not secure the power supply to the cart.

2. The system of claim 1 , further comprising a second clip movable between a securing position, where the second clip secures the power supply to the cart, and a released position, where the second clip does not secure the power supply to the cart, wherein the housing further comprises a second upper clip catch, the base further comprises a second lower clip catch, the second upper clip catch and the second lower clip catch align when the first alignment surface joins the second alignment surface, and the second clip engages the second upper clip catch and the second lower clip catch when in the securing position.

3. The system of claim 2 , wherein the first upper clip catch comprises a first upper crevice, the first lower clip catch comprises a first lower crevice, the second upper clip catch comprises a second upper crevice, and the second lower clip catch comprises a second lower crevice.

4. The system of claim 2 , wherein the first clip is attached to the welding-type power supply or cart via a first spring loaded pin, and the second clip is coupled to the welding-type power supply or cart via a second spring loaded pin, wherein a spring force of the first and second spring loaded pins biases the first clip and the second clip against the welding-type power supply or cart, and wherein the first clip and the second clip are configured to be pulled away from the welding-type power supply or cart by a force acting opposite to the spring force.

5. The system of claim 2 , wherein the base further includes a first sidewall and a second sidewall opposite the first sidewall, wherein the first clip and the first clip catch are positioned on the first sidewall, and the second clip and the second clip catch are positioned on the second sidewall.

6. The system of claim 1 , wherein the welding-type circuitry comprises power conversion circuitry configured to receive input power from a power source and convert the input power to welding-type output power.

7. The system of claim 1 , wherein the first clip is coupled to the first sidewall or a first bezel of the first end wall.

8. The system of claim 1 , wherein the cart further comprises a bottle receiving platform configured to receive a gas bottle.

9. The system of claim 1 , wherein the first clip comprises a first end and a second end, the first end configured to engage the first upper clip catch and the second end configured to engage the first lower clip catch.

10. The system of claim 9 , wherein the first end of the first clip is opposite the second end of the first clip.

11. The system of claim 1 , wherein the spring loaded pin is positioned within a channel of the base.

12. The system of claim 11 , wherein the spring loaded pin includes a head at one end of a shank and a collar at an opposite end of the shank.

13. The system of claim 12 , wherein the head of the spring loaded pin connects to the first clip.

14. The system of claim 13 , wherein the shank of the spring loaded pin is loaded into a center bore of a spring, and the spring abuts the collar of the spring loaded pin and the base of the cart.
