Cartridge-type soldering iron

A cartridge type soldering iron capable of emitting gas, the soldering iron comprising:

• a heater pipe having a tip end and an electrical contact end, the heater pipe having a first hole near the tip end and a second hole near the electrical contact end, the heater pipe having a passage within the heater pipe between the first and second holes to allow gas to enter through the second hole and exit through the first hole;
• and
• a handle base releasably coupled to the electrical contact end of the heater pipe, the handle base adapted to provide power to the electrical contact end and gas to the second hole of the heater pipe, the handle base adapted to substantially seal around the second hole of the heater pipe to substantially prevent the gas from leaking from the cavity.

A cartridge type soldering iron capable of emitting inert gas, the soldering iron comprising:

• a heater cartridge having a heater pipe, the heater pipe having a tip portion and a base portion, the heater pipe adapted to transfer gas and power from the base portion to the tip portion of the heater pipe;
• and
• a handle base having a front cavity and a gas injector, the gas injector adapted to provide gas to the front cavity, the front cavity adapted to receive the base portion of the heater pipe and provide gas and power to the base portion of the heater pipe, and the front cavity adapted to substantially seal around the base portion of the heater pipe so that the gas is substantially prevented from leaking from the front cavity.

A cartridge type soldering iron capable of emitting gas, the soldering iron comprising:

• a heater cartridge having a heater pipe, the heater pipe having a tip portion and a base portion, the heater pipe adapted to receive gas and power from the base portion and pass the gas and power to the tip portion of the heater pipe;
• and
• a handle base having a cavity, the cavity adapted to receive the base portion of the heater pipe to provide power to the base portion of the heater pipe and a sealing means to substantially prevent gas from leaking from the cavity.
