Claim:
1. A heater-sensor sub-assembly adapted for use in a soldering system comprising: an insulating pipe; a heating wire made of first metallic material having proximal end portion, a central winding portion wrapped around said insulating pipe and a distal end portion; a first non-heating wire made of the same first metallic material as said heating wire, said non-heating wire connected to the proximal end of said heating wire; a second non-heating wire made of a second metallic material, said non-heating wire having a proximal end and a distal end with at least a portion of said non-heating wire extending axially through said insulating pipe; a thermocouple formed by connecting said distal end of said heating wire made of said first metallic material connected to a distal end of said second non-heating wire made of said second metallic material; and a third non-heating wire connected to a proximal end of said first non-heating wire, said third non-heating wire made from a metallic material selected from the group consisting of a metallic material having a lower volume resistivity than said first non-heating wire and a metallic material identical to said second non-heating wire.
