TE450 & TE470 are microprocessor welding control unit for suspended resistance welding guns. These control units include specific functions to be used when working with suspended welding guns, such as the double stroke control, and a function checking the efficiency of the safety devices which can be eventually installed on the handle of the machine. It is possible to store 63 different welding programs, 2 programs can be recalled by an external device on the handle. Each program is formed by 18 programmable parameters which describe the working cycle. Besides the simple 4 times cycle, the control units enables to carry out welding processes with pre-weld current, slopes, pulses and post-weld current. The control units can be programmed for working under two different operating modes: standard one and constant current. An integrated ammeter allows to know the welding current used and to set maximum and minimum limits.

• Slope and Pulse functions. Pre-weld and Post-weld currents
• Adjustment of the welding times in half-periods
• Display of the welding current in kA
• Display of the welding current conduction angle
• Double operating mode: standard and constant current
• Welding current limits or conduction angle limits
• Automatic double stroke function
• Stepper function against electrodes wear with programmable increment curve
• Counter of the performed welds
• Compensation of the secondary current to weld oxidised sheets and rods
• Single and automatic cycle
• Delay of first phase shift adjustment, to get the best balance of the machine absorption from mains
