The Weller WTMP MS is compact, powerful, and versatile, designed to boost productivity in industries like electronics, medical, and aerospace. As production accelerates and components become smaller and more complex, the need for precision increases. Surface Mounted Technology (SMT) has become the industry standard, replacing through-hole technology. The Weller RT Micro Soldering Tips offer versatile, high-performance active tips suitable for micro and standard components across a wide range of applications. They are ideal for soldering small and medium components with medium power requirements, especially in aerospace, electronics, military, and automotive industries. For environments requiring IPC standard or MIL-SPEC, potential-free MS versions are available.
