In 4 control modes, according to the different welding conditions to select the optimal method, obtained the best welding effect.
At the same time - average online monitoring of current and voltage, the effective value of power.
Pre pass electrical detection function can be in formal welding Tong state of pre workpiece, effectively reduce the welding defect rate.
Exergy with external interrupt function, can conveniently according to the electrode displacement at any time to stop the electricity, so as to avoid welding excessive heating cause undesirable deformation, stable hot pressure welding
9 - maximum power. Each segment has a slow rise function, effectively inhibit the welding splash.
Can store 15 sets of welding, the workpiece conveniently corresponding to different.
- 2 working frequency (1000Hz/2000Hz), optional flexible adaptation on the market all kinds of high-power inverter welding transformer.
Widely used in the welding of precision components such as large relay contact, motor rotor, copper switch parts.
