<p>A portable electric soldering tool (20) includes a housing (22) having a handle portion (24) and a power head portion (26). A power cord (28) connects the tool (20) to a source of power via a terminal block (36). A main power switch (30) activates the tool (20). A trigger switch (32) in the handle portion (24) intermittently activates a vacuum device (120). A heating assembly (40) includes a heating rod mounted with the heating tip (44) extends from a forward end of the power head (26). The heating rod having an axial bore with a stainless steel lining to prevent solder from building up in the heating rod. A heating coil heats the heating rod. The heating rod directs melted solder into an extraction tube in which a curved wafer is disposed to collect the solder. A diaphragm pump is mounted in the power head and has an oblong piston head, which is mounted with the long axis aligned on a longitudinal axis of the tool, which facilitates a more compact unit.</p> |
