High-Performance 300Amp ARC Welder - IGBT Inverter - China Suppliers Factory - Double Working Station, Soft Start
Detailed Information
Check the internal circuit connection of the welder regularly to make sure that the circuit connection is correct and the connection head is firm (especially the insert connector or component). If rust or looseness is found, sand paper should be used to grind off the rust layer or oxidation film, reconnect it and tighten it. Check all cable insulated leathers regularly for any breakage, or else bind up or replace the cable.
To avoid electrostatic damage to semiconductor components and circuit boards, please wear anti-static devices, or by touching the metal parts of the case to remove static electricity beforehand touching the wiring conductor and circuit board inside the welder.
Avoid water or water vapor entering the welder. Dry it if damped inside. Then, measure the insulation of the welder with an ohmmeter (between the connection nodes and between the connection point and the housing). Be aware that continuous welding is performed only when no abnormalities are found. If the welder is idle for a long time, put it in the original packaging case and stored in a dry environment.

Frequently Asked Questions
How should the internal connections of the welder be maintained?
Regularly check the internal circuit connection to ensure it is correct and firm. If rust or looseness is found, use sand paper to grind off the rust layer or oxidation film, then reconnect and tighten it.
How do I prevent electrostatic damage to the welder's internal components?
To avoid electrostatic damage to semiconductor components and circuit boards, wear anti-static devices or touch the metal parts of the case to remove static electricity before touching the wiring and circuit board inside the welder.
What should I do if water or moisture gets inside the welder?
If moisture enters, dry the inside immediately. Measure the insulation with an ohmmeter (between connection nodes and between connection points and the housing). Resume welding only if no abnormalities are detected.
What are the power requirements for installing the welder?
The welder requires an input voltage of 380V AC±10% 50/60Hz, a 4mm² input cable (length ≤ 3m), and a 63A power switch.
What electrodes are recommended for the ZX7-400G and ZX7-500G models?
The ZX7-400G suggests a maximum electrode size of Φ2.5-4.0mm (on 220V) and Φ2.5-5.0mm (on 380V). The ZX7-500G supports Φ2.5-4.0mm (on 220V) and Φ2.5-6.0mm (on 380V). Both models support acid, alkaline, and stainless steel electrodes.
What standard accessories are included with the welder?
The standard accessories package includes 1x Electrode Holder, 1x Ground Clamp, 1x Welding Mask, and 1x Brush/Hammer.
