Digital AC/DC Square-wave SAW Welding Machine

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

1. CC and CV in both DC welding and AC welding
2. AC CV is recommended for AC quick welding, arc can burns more stably
3. With auto alarmfunction after wire touches the workpieces well, high arc-ignition success rate
4. 4. Duty ratio of 50% and frequency of20-35Hz is recommended
