Weld Controllers.
Merlin Control Systems Ltd design and manufacture a range of accurate, reliable and cost-effective controllers for
resistance welding machines of all kinds, including spot and projection welders, seam welders, wire butt welders,
high-speed contact welders, and specials, with a power against time profile for applications such as grating welding.
These units are microprocessor based, and designed for ease of use by unskilled staff. All standard units have eight
internally stored sets of weld parameters (welding programs), one of which is selected for use by bcd coded inputs,
either from a manual switch, or from a PLC.
Two primary types are available. The standard model, intended for front panel mounting, has only two pushbuttons,
and an LED display. The operator is guided through a simple set-up proceedure to input his required weld settings
for all eight programs.
Our newer model includes an RS232 interface, and is intended to be internally mounted on the DIN rail of a control
cabinet - no metalwork required. All the same features and options are available, but welding parameters are downloaded
from a PLC or HMI, as required.
