Q1. What makes ZX7-315SiC different from a normal MMA welder? A1. ZX7-315SiC uses SiC inverter technology, which is positioned for efficient output, stable arc control, lighter weight, and stronger performance than many basic entry-level stick welders. Q2. What input voltage does it support? A2. The welder supports 220V/380V input at 50/60Hz, allowing it to work in both workshop and industrial power environments. Q3. What output current can it deliver? A3. The listed welding output is 180A on 220V and 230A on 380V, making it suitable for heavier repair and fabrication than small home-use welders. Q4. What is the duty cycle? A4. The machine is listed with a 100% duty cycle at 40°C, which is valuable for professional users who need longer welding time and dependable operation. Q5. What electrode sizes are suitable? A5. It supports 2.5-4.0mm electrodes on 220V power and 2.5-5.0mm electrodes on 380V power, giving users flexibility for different material thicknesses. Q6. What material thickness can it weld? A6. The listed welding thickness is 0.8-12mm. Actual welding performance depends on material preparation, electrode selection, welding position, and operator skill. Q7. Is this welder portable enough for field work? A7. Yes. The machine weighs about 1.95kg, making it highly portable for repair teams, maintenance crews, installers, and contractors working between sites. Q8. Does it require shielding gas? A8. No. It is an MMA stick welder, so it uses coated electrodes and does not need external shielding gas. Q9. What accessories are included? A9. The package includes a 3m 500A 25mm² electrode holder cable and a 2m ground cable, matching the machine's professional positioning. Q10. Who is the ideal buyer for this machine? A10. It is ideal for professional repair users, steel fabrication shops, construction maintenance teams, and distributors looking for a compact high-performance SiC welder. |
