Features

1. Full Netcom Voltage

220v/380v full Netcom, no need to worry about using generator

Bring a higher quality welding experience

2. Smart boot

When the welding machine is turned on, the impact on the power grid is small

Automatic detection of input current and voltage, output voltage, it is true smart soft start

3. Force control

Effectively improve arc penetration during welding and deeper penetration

4. Smart fan

Strong heat dissipation, excellent energy saving

5. Heavy-duty technology

Full load welding in 40℃ environment can achieve 100% duty cycle

120% duty cycle can be achieved for full load welding in a 30℃ environment

Effectively improve work efficiency

6. Innovative technology

Strongly replace the traditional inverter DC ARC welding machine

Lengthened output 100m welding wire for normal welding

7. Hot start control

Especially suitable for low-carbon steel J422, alkaline (J427, J506, J507, etc.) electrodes that are easy to arc

8. LCD display

Function display is more intuitive

The interface is more harmonious

9. Spot welding mode

Intelligently control the arc length to prevent the arc from burning the eyes

10. Pulse ARC welding

Welding spatter is obviously less than ordinary ARC welding

Significantly improved weld quality

11. Applicable to all welders

Pulsed arc automatically and rhythmically push the electrode forward

Unused welders also can weld fish-scale welds

12. 32-bit microcontroller

Program calculation ability is better

The whole machine is more stable

13. Lifting TIG welding

Arc starting does not stick to the workpiece

Effectively reduce the loss of tungsten needles

The arc starting success rate is over 99%

14. Powerful functions

Pulse Lift TIG up and down slopeof current

Basic current/frequency/duy ratio of pulse can be adjusted

15. Anti-sticking control

Adopt a new generation of anti-sticking technology

Efficiently solve the problems of arc welding rod sticking to the workpiece

16. Welding special electrodes

Our pulse MMA welding machine can weld all special electrodes, especially E7018 low hydrogen heat resistant steel electrode and Boho fox cel E6010 cellulose electrode

17. Multi-core check protection

When the machine encounters a fault, it will automatically protect the machine and display the fault code

Screen display code Code reminder Cause of problem Screen display code Code reminder Cause of problem
r01 overheated Dust removal and inspection of fan r05 Undervoltage Check input voltage
r02 Overpressure Check input voltage r06 Abnormal temperature control Or check the harness
r03 Double pressure anomaly Check the input voltage and try to turn it on and off again r07 Hall anomaly Or check the harness
r04 No load abnormality Check the output signal line or MUR and transformer r08 internal fault Please contact dealer
