Remotely controllable current regulator apparatus

Claim 1

A REMOTELY CONTROLLABLE CURRENT REGULATOR FOR SUPPLYING CURRENT TO WELDING EQUIPMENT COMPRISING INPUT MEANS ADAPTED TO BE CONNECTED TO A SOURCE OF CONSTANT ELECTRICAL POTENTIAL, OUTPUT MEANS ADAPTED TO BE CONNECTED TO WELDING EQUIPMENT, FIRST RESISTANCE MEANS COMPRISING A PLURALITY OF RESISTANCES EACH CONNECTED IN PARALLEL WITH ONE ANOTHER AND IN SERIES BETWEEN SAID INPUT MEANS AND SAID OUTPUT MEANS, SEPARATE INDIVIDUALLY, MANUALLY CONTROLLABLE SWITCH MEANS OPERATIVELY ASSOCIATED WITH EACH OF SAID RESITANCES FOR SELECTIVELY CONNECTING EACH OF SAID RESISTANCES WITH SAID OUTPUT, SAID RESISTANCES PROVIDING RATHER LARGE STEPS IN THE AMOUNT OF AMPERAGE PROVIDED THRERETHROUGH, SECOND RESISTANCE MEANS CONNECTED WITH SAID INPUT MEANS, REMOTELY OPERABLE SWITCH MEANS INCLUDING A COMMON CONTACT MEANS AT ONE SIDE THEREOF CONNECTED WITH SAID OUTPUT MEANS AND A PLURALITY OF SEPARATE CONTACTS INSULATED FROM ONE ANOTHER AND CONNECTED WITH DIFFERENT PORTIONS OF SAID SECOND RESISTANCE MEANS TO PROVIDE DIFFERENT AMOUNTS OF ELECTRICAL CURRENT IN RELATIVELY SMALL INCREMENTS TO SAID SEPARATE CONTACTS, MOVABLE CONTACT MEANS FOR SELECTIVELY CONNECTING DIFFERENT ONES OF SAID SEPARATE CONTACTS WITH SAID COMMON CONTACT MEANS AND SAID OUTPUT MEANS SO THAT SAID SEPARATE CONTACTS ARE IN SERIES BETWEEN SAID INPUT AND SAID OUTPUT MEANS AND IN PARALLEL WITH SAID FIRST RESISTANCE MEANS, AND MEANS FOR REMOTELY CONTROLING THE MOVEMENT OF SAID MOVABLE CONTACT MEANS FOR SELECTIVELY ENGAGING DIFFERENT ONES OF SAID SEPARATE CONTACTS AND REMAINING IN ENGAGEMENT WITH A DESIRED SEPARATE CONTACT AS LONG AS DESIRED TO PROVIDE FINE ADJUSTMENTS OF AMPERAGE AND TO ENABLE A DESIRED ADJUSTED AMPERAGE TO BE MAINTAINED AT SAID OUTPUT MEANS AS LONG AS DESIRED AND FURTHER WHEREIN SAID AMPERAGE MAY BE READILY INCREASED OR DECREASED AS DESIRED.
