In electric arc-welding, it is now the standard practice to use coated or coveredelectrodes, the

These doors may carry ing covered arc-welding electrodes, while 2 is an labels designating the type or size of electrodes to auxiliary cabinet preferably permanently fasbe found in the various compartments. For that tened as by welding to the main cabinet i. The matter, the compartments where a single door is cabinet i is divided into a plurality of compartused, as in Figure 1, may be interiorly labeled so ments by a series of shelves 3 which may be fiat that when the door is opened the welder may see metal plates having ventilating holes 5 therein, the proper designation of the electrodes he deor the shelves may be of the screen type 5 such akes to use. asshown inFigure 7.

Preferably, a sealing gasket 28 is used for the main door II as shown in Figure 4.

In Figure 8, the compartments II are spaced from the side walls of the cabinet where the heating chamber I is of a form which passes around at least two sides of the compartments.

While I have shown a storage and treating structure especially adapted for use with enginepropelled vehicle repair shops, the cabinets may be utilized in other places where there is a source of heat for passing through the heating chamber. Hence, I do not want to be unduly limited in the interpretation of the appended claims.

What I claim is:

1. Conditioning means for covered arc-welding electrodes used in field service on an engine propelled vehicle repair shop, said means comprising a cabinet having two vertically spaced rows of shelf type compartments to receive electrodes, the shelves having ventilation openings therein, each compartment having its own door, at least the top and bottom doors provided with air chambers to pass air into the compartments through the openings in said shelves, a heat transferring chamber centrally located between said rows oi compartments and extending straight across the cabinet with its rear wall terminating in close proximity to the rear wall or the cabinet thereby forming a small space chamber thereat, means for passing heat coming from said engine to and from said heating chamber and means for ventilating the compartments, the ventilation being assisted by transverse passages connecting the compartments on one side of the heating chamber with the corresponding compartments on the other side by way of said space chamber. v

2. A structure for carrying and conditioning covered arc-welding electrodes in an enginepropelled vehicle repair shop comprising a steel cabinet adapted to be fastened to the framework of the vehicle, the cabinet having a centrally located closed heating chamber extending clear across one dimension of the cabinet and welded to at least one of its walls, compartments having perforated shelves fastened to the side walls of the cabinet and to the heating chamber, a door for said compartments, said door having means defining a ventilating chamber open at one end, said" door having openings therein for admitting air from said ventilating chamber to said compartments, means for circulating engine exhaust gases through said heating chamber, and means for venting said compartments.
