BMK-16W  Stud Welding System

The PH-2L is the standard gun for the BMK-16W Stud Welder


The BMK-16W stud welder is very powerful, but compact and portable. Weld parameters are set using a membrane keyboard and display. Unlike the 2 models shown above, the BMK-16 allows adjustment of all the weld parameters including the weld current. Microprocessor control and programmability assures consistent weld sequences. This machine automatically controls inert shielding gas delivery to the weld zone. The 1000 amp adjustable and regulated power source can weld fasteners up to 5/8" diameter with reduced base. This system features the ability to adjust the pre-arc time to weld to dirty or oily surfaces. The amount of shielding gas that flows prior to welding is also adjustable. The unit has advanced safety features to protect the operator. The lift and pre-arc functions can be tested without welding current. The system can be fitted with a module to support automatic or semi automatic stud feeding. The system can also be controlled via a CNC interface.

The BMK-16W Stud Welding System also has the process-monitoring quality control system as an option. The welding parameters are measured by the system and are printed out via external software. The system can also detect if the parameters are out of  a set range and set off an error condition. This will alert the operator of a potential problem weld and allow the operator to correct the situation. This saves time and money, and may be a requirement for ISO 9001 quality assurance programs.
