초록 ▼

In a preferred embodiment, a portable wire feed electric arc welder, including a cabinet, a welding gun connected to the cabinet through a flexible conduit, and a supply mechanism to continuously feed the wire to the welding gun. There is a mechanism to receive either AC or DC power into the welder and a selector mechanism to selectively switch between a first mode of operation in which welding is performed with an external DC source, a second mode of operation in which welding is performed with an external AC source, and a third mode of operation in which welding is performed with an internal AC source. The internal AC source includes a step-down transformer connected to a conventional 115 VAC power source.

대표청구항 ▼

A portable wire feed electric arc welder, comprising: a cabinet; a welding gum connected to the cabinet through a flexible conduit; supply means to continuously feed said wire to said welding gun; means to receive either AC or DC power into said welder; a selector switch having a plurality of contacts associated therewith; a 12 VDC control circuit having a first relay coil connected in series with a first set of said plurality of contacts; a 115 VAC control circuit having a second relay coil connected in series with a first set of relay contacts associated with said first relay coil, said second relay coil becoming energized and closing a second set of relay contacts whenever said first set of relay contacts are closed by energization of said first relay coil; a second set of said plurality of said contacts connected in parallel with said second set of relay contacts associated with said second relay coil, both of which are connected in series between a power source and a positive welding conductor; a third set of said plurality of contacts connected to the primary side of said step-down transformer and a fourth set of said plurality of contacts connected to the secondary of said step-down transformer; whereby in a first mode of operation, said selector switch is placed in a first position, causing said second set of said plurality of contacts to be closed, thereby creating electric potential at said positive welding conductor; in a second mode of operation, said selector switch is placed in a second position, causing said first set of said plurality of contacts to be closed, thereby creating electric potential at said positive welding conductor only when said first relay coil is energized; and in a third mode of operation, said selector switch is placed in a third position, causing said first, third, and fourth sets of said plurality of contacts to be closed, thereby creating electric potential at said positive welding conductor only when said first relay coil is energized.
