SAFCO is a leading company in the development and manufacture of resistance welding centres that provide a wide range of high quality assurance controls. The SAFCO controls enable monitoring of a large number of welding parameters and the management of various work modes which, when added to the ease of network communications, turn it into the ideal control for implementing into production lines and management networks in plant production. The SAFCO controls can be managed through a PLC or via any field bus, allowing them to be seen as a network node. There are two lines of SAFCO controls:
These are ac controls for resistance welding machines. These controls include the innovative CS-NET, which comprises two different units, one for programming and the other for power and control. The high communications speed between two devices allows programming data to be transmitted with minimum waiting time for the user. The processor allows the unit to be employed in ac applications for seam and spot welding through the management of I/O, communications and of the power unit that performs welding current regulation through diode phase control.
Medium frequency controls
In this case, they are controls for resistance welding machines with inverter technology. The CS-I consists of two different units, the programming and display unit and the power and control unit. The high communications speed between these devices allows programming data to be transmitted with minimum waiting time for the user. The processor allows the management and control in ac applications for seam and spot welding through the management of I/O, communications and of the power unit that performs welding current regulation through a medium frequency inverter group control, which permits faster and more efficient welding operations.
PEI welding machines
PEI equipment is renowned for their quality and reliability and is available in a wide variety of products: clips, columns, seams and a varied range of accessories and capacities. The equipment incorporates intuitive controls, with management of the main welding parameters and the option to load job tables and download results data by USB. PEI has two differentiated lines:
This line includes clips and spot-welders with applications that are mainly aimed at car repair work. This equipment also has a clear application in the construction industry for welding thin metal sheets and galvanised steel. . The AS25-15K inverter unit may be presented as representative equipment in this line. This equipment is intended for car repair work and is optimised for welding high-strength carbon and galvanised steels. Because of the inverter technology, the welding quality and reliability are increased, which also applies to equipment power consumption savings.
PEI has a wide selection of spot-welders and columns available with application in general industry, in cars as well as in construction and domestic appliance manufacture. The latest PEI development, the PFP 381 inverter, is representative of this line, which is able to cover industrial demands that allow its simple adaptation and integration into the production environment.
Tesol is a distributor for INTEC, a manufacturer with wide experience in nut feeders. This equipment permits simple integration into the welding equipment supplied by Tesol and facilitates its putting into operation in high-production lines.
