• a housing;
• an end portion;
• a soldering tip coupler;
• a soldering cartridge coupler, which is different than the soldering tip coupler;
• a soldering tip configured to be coupled to the end portion of the soldering iron hand piece via the soldering tip coupler, the soldering tip configured to be used at a first thermal demand;
• a soldering cartridge configured to be coupled to the end portion of a same soldering iron hand piece via the soldering cartridge coupler as the soldering iron hand piece used with the soldering tip, the soldering cartridge configured to be used at a second thermal demand, which is a different than the first thermal demand of the soldering application;
