Digital Inverter Tri-wire Tri-arc SAW Welding Machine

 Our Tri-wire tri-arc SAW machine is developed based on the all-digital submerged arc welding machine.

One system include one MZ7-1600 DC submerged-arc power source and two sets of MZE-1250 AC/DC square-wave submerged-arc power sources,and one three-wire welding tractor as well as one control panel.

Features：

▉ Both power source and tractor DSP all-digital control and digital communication

▉ With expert database, and 30 saving channels

▉ Digital display and presetting of current, voltage and marching speed

▉ AC frequency, duty ratio adjustable

▉ AC/DC power source and DC power source work simultaneously without affecting each other

Technical Features：

1. DC power source goes ahead, and AC/DC power source flows, which guarantee good appearance and good weld
2. In welding, the given welding parameters of DC power source should be bigger than or equal tothat ofAC/DC power source
3. After grating feedback control, wire feeding will be more stable and can speed up before resistance, especially suitable for barrel wire
4. With auto warning function after wire touches the workpieces well, high arc-ignition success rate
5. Duty ratio of 50% and frequency of 15-30 is recommended
6. Suitable for high-speed high-efficiency welding of thick plate and ultra-thick plate
7. Especially suitable for using in petrol tube, gas tube, ship making, wind tower, and son on
