Abstract
A system and method for determining the approximate weight of metal consumables used by an electric arc welder over a period of welding time, the system comprises a program to calculate the total energy exerted by the welder over a period of welding, a divider to divide the total energy by a number including a power of a selected non-unity factor to obtain said weight. When the energy is in mega joules the factor is in the range of 3.2–4.2 and preferably approximately 4.0.
Claims18
A system for determining the approximate weight of metal consumable used by an electric arc welder over a period of welding time, said system including a sensor reading arc current, a sensor reading arc voltage, a multiplier to obtain weld power, a weld time multiplier of said weld power to obtain representation of the total expended joules over said period of welding time, a divider circuit to divide said joules by 1 million to obtain a representation of mega joules and a divider circuit to divide said arc current, said arc voltage, said weld power, said weld time, said joules or said mega joules representation by a selected factor in the range of 3.2 to 4.2 to obtain a value indicative of said approximate weight.
A system for determining the approximate weight of metal consumable used by an electric arc welder over a period of welding time, said system comprising a circuit to calculate the total energy exerted by said welder over a period of welding, a divider to divide said total energy by a number including a power of a selected non-unity factor to obtain said weight, said number including the power of the selected non-unity factor being of value which directly obtains said weight.
A method for determining the approximate weight of metal consumable used by an electric arc welder over a period of welding time, said method comprising:
- (a) reading arc current;
- (b) reading arc voltage;
- (c) multiplying said arc current with said arc voltage;
- (d) multiplying said weld power by weld time to obtain a representation of the total expended joules over said period of weld time;
- (e) dividing said joules by 1 million to obtain a representation of mega joules and,
- (f) dividing said arc current, said arc voltage, said weld power, said weld time, said joules or said mega joules representation by a selected factor in the range of 3.2 to 4.2 to obtain a value indicative of said approximate weight.
A method for determining the approximate weight of metal consumable used by an electric arc welder over a period of welding time, said method comprising:
- (a) calculating the total energy exerted by said welder over a period of welding;
- (b) dividing said total energy by a number including a power of a selected non-unity factor to obtain said weight, said number including the power of the selected non-unity factor being of a value which directly obtains said weight.
