The soldering tip RTU 004 C MS from Weller is a highly specialized needle tip, specifically designed for use with the soldering iron WXUP MS. This tip features a conical shape with a diameter of 0.4 mm and a length of 27.5 mm. As part of the RTU series, it is exclusively designed for use with MIL-SPEC-compliant soldering irons. The MIL-SPEC version of the RTU 004 C MS meets the strict requirements of the MIL-STD-2000 standard. A key feature of this soldering tip is its additional insulation to ground, which effectively prevents interference frequencies, thus ensuring higher precision and safety in soldering tasks. Due to these specifications, the soldering tip is not compatible with conventional handpieces and should only be used with corresponding MS soldering irons. This makes the RTU 004 C MS an ideal choice for technical applications requiring the highest precision and reliability.
