ZX7-400M2: Ideal for medium-thick plate welding, 2.5–4.0mm electrodes, daily steel structure and mechanical processing work, cost-effective for regular industrial tasks.
ZX7-500M2: Upgraded industrial grade version, supports up to 5.0mm electrodes, stronger current output, higher duty cycle, more suitable for thick plate welding, shipbuilding, petrochemical and long-time continuous welding work.
Q1: Does this machine support TIG welding?
Yes. It adopts Lift-TIG ignition mode, no scratch start required, no tungsten contamination, ensuring cleaner welding results.
Q2: Can the welding cable be extended for long-distance operation?
Yes. This machine supports arc force adjustment, maintaining stable current even with extended cables, meeting the needs of long-distance jobsite welding.
Q3: Does it support long-duration continuous welding?
Yes. Equipped with large-capacity capacitors, multiple protection features, and a high-duty-cycle design, it supports stable continuous welding for extended periods.
Q4: What is the difference between ZX7-400M2 and ZX7-500M2? How to choose?
The main differences lie in output power and application scenarios. ZX7-400M2 is suitable for conventional structural components and medium-thick plate welding, with a maximum electrode diameter of 4.0mm. ZX7-500M2 offers higher power, ideal for thick plates and long-duration continuous welding, supporting electrodes up to 5.0mm. For general projects, choose ZX7-400M2; for thick plates and heavy-duty work, choose ZX7-500M2.
Q5: Is it easy for beginners to operate?
Yes. Simple operation with single-knob adjustment and digital current display, stable arc ignition and low spatter, suitable for both beginners and experienced welders.
Q6: Can it be used on job sites with unstable power supply?
Yes. This machine adopts high-power imported IGBTs with strong anti-interference capability, combined with passive power factor correction technology, making it adaptable to complex power supply conditions on construction sites.
