Our all-digital AC/DC square-wave SAW machine is developed on the DC SAW machine adopting the inverter technology twice, with wonderful welding result. The details is: the 3-phase 380V/50Hz power will change into HF AC after the filtration of the power frequency rectifier and role of inverter. And over high-frequency transformation and rectification, feedback control of output signal, the smooth and continuously adjustable DC will be got. After the second inversion, the DC will be changed into low-frequency AC for automatic welding of work pieces.
Features
▉ Both power source and tractor DSP all-digital control and digital communication
▉ With expert database, and 30 saving channels
▉Menu and functions LCD display and control, easy to operate
▉ Start-arc anti-stick, auto wire back while arc stops
▉ Digital display and presetting of current, voltage and marching speed
▉ Support MMA, SAW and gouging
▉ AC frequency and duty ratio adjustable
Technical Features
- CC and CV in both DC welding and AC welding
- AC CV is recommended for AC quick welding, arc can burns more stably
- With auto alarmfunction after wire touches the workpieces well, high arc-ignition success rate
- 4. Duty ratio of 50% and frequency of20-35Hz is recommended
