High Performance 300Amp ARC Welder - IGBT Inverter Portable Welding Machine from China Suppliers & Factory
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 often should I inspect the welder's internal circuit connections?
You should check the internal circuit connection of the welder regularly. Ensure the connection is correct and the connection head is firm, especially the insert connector or components. If rust or looseness is found, use sandpaper to grind off the oxidation layer and tighten it.
How do I prevent electrostatic damage to semiconductor components?
To avoid electrostatic damage, wear anti-static devices or touch the metal parts of the welder case to remove static electricity before touching any wiring conductors and circuit boards inside the machine.
What should I do if water or water vapor gets inside the welder?
If moisture enters, dry the welder interior immediately. Measure the insulation with an ohmmeter between the connection nodes, and between the connection point and the housing. Do not resume welding until no abnormalities are found.
What are the main advantages of the IGBT inverter technology used in these machines?
The machines adopt the latest mature IGBT full-bridge inverter technology, offering stable welding with both acid/alkaline and stainless steel electrodes, adjustable thrust current to prevent sticking, and comprehensive protection functions against overcurrent, overheating, and undervoltage.
What are the essential requirements for installation?
Installation requires an input voltage of 380V AC±10% 50/60Hz, a 4mm² input cable (length ≤ 3m), and a 63A power switch. Additionally, the ambient temperature should be between -10℃ and +40℃ with no blockage on air inlets/outlets.
