Frequently Asked Questions
What input voltage options are supported by the ZX7 series welding machines?
The machines support dual voltage configurations of AC 220V/380V at 50Hz/60Hz. Please pay attention to the junction box tips for correct wiring and voltage selection.
Can these inverter welders be used with an engine-driven generator?
Yes, they can be operated with a generator. However, the generator output power must be at least 1.5 times the rated input power of the welding source, and a bucking coil should be used.
What types of welding electrodes are recommended?
These units are compatible with acid, alkaline, and stainless steel electrodes (such as E6013). The recommended maximum electrode size is Φ2.5-3.2 for the ZX7-308K and Φ2.5-4.0 for the other models.
What built-in safety protection features are included?
The machines feature comprehensive built-in protection systems, including undervoltage, overcurrent, and overheating protection to ensure safe and reliable operation.
What are the recommended environmental conditions for operation and storage?
The working ambient temperature range is -10°C to +40°C, and the storage range is -25°C to +55°C. Ensure the working environment is well-ventilated, dry, and protected from dust, rain, and direct sunlight.
What accessories are included in the standard package?
The standard package includes 1x Electrode Holder, 1x Ground Clamp, 1x Welding Mask, and 1x Brush/Hammer. Optional accessories like welding helmets, gloves, and TIG torches are sold separately.
