High Performance 300Amp ARC Welder - Portable IGBT Inverter from China Suppliers & Factory for Engineering Construction
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
What input voltage is required for the ZX7 welder installation?
The standard input voltage required is 380V AC±10% at 50/60Hz. Make sure to use a 4mm² input cable with a length of ≤3m and a 63A power switch.
How do I prevent electrostatic damage to the internal components?
Before touching any wiring conductors or circuit boards inside the welder, always wear anti-static devices or touch the metal parts of the welder's case to discharge static electricity safely.
What should I do if water or moisture gets inside the welding machine?
If moisture enters, dry the welder interior thoroughly. Before resuming operation, measure the insulation resistance using an ohmmeter between the connection nodes and between the connection points and the housing. Only proceed if no abnormalities are found.
What standard accessories are provided with the welder package?
The standard package includes 1x Electrode Holder, 1x Ground Clamp, 1x Welding Mask, and 1x Brush/Hammer.
What safety protection features does the welder have?
The welding machine is equipped with complete built-in protection systems including undervoltage protection, overcurrent protection, and overheating protection to ensure safe operations.
Can I use this machine for Lift TIG welding?
Yes, Lift TIG welding is supported, but you will need to purchase the Lift TIG Torch separately as it is listed as an optional accessory.
