Control units

Upgrading an older machine with a new Control unit can be a good alternative to buying a new machine if the machine otherwise is working fine.
We have complete kits for embedded or seperate boxes.

Welding control TE550

Svetsvakt TE550 The TE550 is a microprocessor-based welding control unit for resistance welders. The task of the welding control unit is to manage the welder components, in particular the controlled diodes that carry out the welding current adjustment. The TE550 is a particularly versatile welding control unit as it may be adjusted to different types of welders; it may be installed not only on spot and projection welders but on seam welders too. It may work with power adjustment: both in constant current and in constant energy (optional). The number of inputs and outputs may be increased so to better adjust the welding control unit to automatic machines. It is possible to store up to 250 different welding programs, 31 of which are recalled directly from an external device. Each program comprises several programmable parameters that describe the work cycle. In addition to the plain 4-stage welding cycle, the control unit allows the running of welding processes with pre-welding current, post-welding current, slope and pulses.

Welding control TE101

Svetsvakt TE101-TECNA It is a particularly versatile welding control unit as it may be used in a wide range of welding applications, both in manual welders (manual and pneumatic operated) and in automatic welding systems. The integrated ammeter and the welding current control limits function allow an easier adjustment and allow the checking of the welding quality.
