Smart welding helmets with arc time tracking verification and lens maintenance detection

A welding helmet, comprising:

• processing circuitry;
• and
• memory circuitry comprising machine readable instructions which, when executed, cause the processing circuitry to:
• determine whether an operator is performing a welding operation based on at least one of a welding signal, a measured wire feed speed, a measured gas flow rate, a distance from the welding helmet to a light source, whether the welding helmet is mounted on a head of the operator, or whether the welding helmet is in an up or down orientation over a face of the operator, and
• track an arc time or darken a filter of the welding helmet in response to determining that the operator is performing the welding operation,
• wherein determining whether the operator is performing the welding operation based on the welding signal comprises:
• receiving the welding signal from a welding power supply, a wire feeder, a gas valve, or a welding tool,
• wherein determining whether the operator is performing the welding operation based on the measured wire feed speed or the measured gas flow rate comprises:
• receiving a wire feed speed measurement or a gas flow rate measurement from the welding power supply, the wire feeder, the gas valve, or the welding tool,
• wherein determining whether the operator is performing the welding operation based on whether the welding helmet is mounted on a head of an operator comprises:
• determining whether a capacitive sensor of the welding helmet detects skin contact, determining whether a carbon dioxide sensor of the welding helmet detects a carbon dioxide level above a CO2 threshold, determining whether an oxygen sensor of the welding helmet detects an oxygen level below an oxygen threshold, or determining whether an optical sensor detects an optical signal transmitted across a space that would be filled by the head of the operator if the welding helmet was mounted on the head of the operator, and
• determining that the operator is performing the welding operation in response to determining that the capacitive sensor detects skin contact, the carbon dioxide sensor detects the carbon dioxide level above the CO2 threshold, the oxygen sensor detects the oxygen level below the oxygen threshold, or the optical sensor does not detect the optical signal, and
• wherein determining whether the operator is performing the welding operation based on whether the welding helmet is in an up or down orientation over a face of the operator comprises:
• determining whether a carbon dioxide sensor of the welding helmet detects a carbon dioxide level above a CO2 threshold, determining whether an oxygen sensor of the welding helmet detects an oxygen level below an oxygen threshold, or determining whether an optical sensor detects an optical signal transmitted across a space that would be filled by the head of the operator if the welding helmet was in a down orientation, and
• determining that the operator is performing the welding operation in response to determining that the carbon dioxide level is above the CO2 threshold, the oxygen level is below the oxygen threshold, or the optical sensor does not detect the optical signal.
