The Pro32 is a staple tool for the hobbyist, tinkerer, or electrical engineer.  Featuring a sleek body, complete with temperature adjustment buttons and an OLED display, the Pro32 feels good in the hand and offers a wide temperature range for operation.  Its internal heating element warms up to operating temperature in just 12 seconds!

Rapid Warmup

With the help of dual temperature sensors, the internal heating element reaches its operating temperature extremely fast—just 12 seconds!  The tip temperature can be set between 212° F and 752° F (100° C to 400° C) using the adjustment buttons and OLED display.

New Power Supply Design

The Pro32 features an integrated DC5525 12-24V connection.  Its anti-static design isolates the temperature sensors from extraneous surges.

Tough & Portable

The sleek, slim design is comprised of an SAE 304 stainless steel core, housed inside a polycarbonate shell with an easy-to-read OLED display.

Smart & Safe

The integrated STM32 processor chip automatically regulates the Pro32’s “sleep mode”, “standby”, and “operating mode”, ensuring the safety of the user.

ST-M5045 is a cost effective, high performance bi-polar two phase micro-stepping drive applying pure-sinusoidal current control technique. It is best suited for the applications that desired extreme low noise and heat. It operates well in an environment, where electricity supply experience instability and fluctuation
