Abstract

An arc welder, designed to receive its source of power from a vehicle'"'"'s alternator through a special controlled battery charger. The first portion of energy used in welding comes from the vehicle'"'"'s battery charger and the balance of energy used in welding comes from the welder'"'"'s battery pack. Between spurts of actual welding, the welder'"'"'s batteries are re-charged by the vehicle'"'"'s special controlled battery charger. The batteries in said battery pack are so arranged as to give the operator a choice of voltage for welding and inductors are used to control the current. Also, the batteries can be used direct by by-passing said inductors for extra-heavy cutting and/or extra-heavy duty welding thus giving the operator an extremely wide range of current to fit his needs.

Claims

1. A vehicular arc welder comprising:

a battery pack comprised of four series connected individual batteries, the battery pack including a terminal connected at each pole of the jack and including two other terminals, each connected to an interconnection of individual batteries in the battery pack;

each of said terminals of the battery pack having two single conductor taper lock type jacks connected thereto, whereby two separate jack plugs may be selectively connected to each terminal;

a battery charger having two output cables each connected to a jack plug, these two jack plugs connected to two selected terminals of the battery pack, each plug being plugged into one of the two jacks at each terminal;

an inductive means comprised of twelve inductors connected in series, each interconnection of the inductors and the end of the first inductor which is not connected to another inductor being connected to a single conductor taper lock type jack, the end of the twelveth inductor which is not connected to another inductor being connected to a jack plug, this jack plug of the inductive means being plugged into one of the two jacks at a selected terminal of the battery pack,

two welding cables, one welding cable having a workpiece clamp connected at one end and having a jack plug at the other end, this jack plug being plugged into one of the two jacks at a selected terminal of the battery pack, the other welding cable having an electrode holder connected to one end and a jack plug at the other end, this jack plug being plugged into a selected one of the jacks of the inductive means.

2. A vehicular arc welder according to claim 1 further including means for installing said arc welder in an automobile type vehicle.

3. A method of welding or cutting with a vehicular arc welder comprising the following steps:

providing power from a vehicle'"'"'s alternator to a battery charger;

providing a battery pack comprised of four individual batteries connected in series;

providing a changeable connection of said battery charger to selected batteries in the battery pack;

providing an inductive means with plural output terminals to allow for the selection of plural inductance values;

changeably connecting one terminal of said inductive means to a selected battery in the battery pack;

changeably connecting a workpiece to a selected battery in the battery pack whereby the above mentioned connections to the battery pack determine the voltage level for the welding or cutting operation;

changeably connecting an electrode to a terminal in the inductive means to select a current used for the welding or cutting operation;

performing the welding or cutting operation.

4. The method of claim 3 further including the step of bypassing the inductive means by connecting the electrode directly to a selected battery or the battery pack, thereby providing a high current for heavy duty welding or cutting.
