The BMK-12W SOYER stud welder with outstanding quality and performance features represents the current and future state of stud welding technology. The all-digital stud welder with computer intelligence guarantees absolutely uniform and reproducible functional sequences for optimum welding results. The modular construction of useful and easy-to-service compact housing, the modern design and progressive technology provide the SOYER stud welder with its unique appearance. The BMK-12W stud welder is universally applicable and combines 3 different stud welding methods in a sturdy compact case.
■ Drawn arc stud welding
■ Stud welding with protective gas
■ Short-cycle drawn arc stud welding

Additional performance features of the BMK-12W stud welder include:

■ Development and production fulfil all prescribed safety targets such as
   - The latest safety and accident prevention regulations 
     (Act on the Safety of Technical Working Equipment)
   - Electromagnetic compatibility (EMC Act)
   - European regulations (EU Directives on Machinery)

■ Certificate proof of mentioned safety targets

■ Simplest operator guidance via highly sophisticated membrane             keyboard with clear symbols for all necessary parameter inputs

■ GS/CE/S emblem for verified safety

■ Shielding gas preflow time variably adjustable

■ Preweld current time variably adjustable

■ Welding time variably adjustable

■ Integrated gas operating facilities

■ Easy to carry and ideal for mobile application

■ Optional simple and low-cost retrofitting possibility with an automatic         module for semi and fully automatic stud feed

■ Interface for signal interchange with external controls

■ LED display panel with the control function of all operational states

■ Integrated self-protecting device in case of excess temperature or excessive               welding sequence

■ Computer check on operability and simulated program run of all setting                     parameters on stud welder and gun without welding current

■ New abrasion proof, scratch-resistant and antisoiling plastic film coating on the            front panel to protect all inscriptions even after many years of use

■ Table on the front panel indicating standard values for all common stud types and   diameters

■ Operating range with short-cycle drawn arc welding: M3 - M12RD or Ø 2 - 11 mm

■ Operating range with shielding gas operation: M3 - M12RD or Ø 2 - 11 mm
