The new BMK-16i SOYER stud welder with outstanding quality and performance features represents the 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 in useful and easy-to-service compact housing, the modern design and progressive technology provide the SOYER stud welder with its unique appearance. The BMK-16i stud welder is universally applicable and combines in a compact case the following stud welding methods

■ Drawn arc stud welding
■ Stud welding with protective gas
■ Short-cycle drawn arc stud welding

and welding systems

■ Stud welding
■ Nut welding
■ Electrode welding
■ TIG welding

Additional performance features of the BMK-16i 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 Directive on Machinery)

■ Certificate proof of mentioned safety targets

■ Extremely simple operator guidance via sophisticated membrane keyboard with clear symbols for all necessary parameter inputs

■ CE mark and safety mark for verified safety 

■ Welding current variably adjustable

■ Shielding gas preflow time variably adjustable

■ Welding time and preweld current time variably adjustable

■ High-dynamic regulation of the welding process

■ High clock frequency of 30 kHz

■ Integrated inert gas operation mode 

■ Low connected load and low weight

■ High welding current of 1000 A for stud welding

■ High welding current of 300 A for electrode welding and 100 A for TIG welding
■ Constant current controller (current fluctuation control)

■ Interface for signal interchange with other external control systems (optional simple and low-cost retrofitting possibility with an automatic module for semi- and fully automatic stud feed)

■ LED display panel with control function of all operational states

■ 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 abrasionproof, scratch-resistant and anti-soiling plastic film coating on the front panel to protect all inscriptions even after many years of use

■ Table at the front panel showing standard values for all common stud types and diameters

■ Integrated quality control (option)
