ARC-250A/400A MMA Welder

Our ARC-250A/400A MMA welder makes use of advanced single-tube IGBT half-bridge inverter technology. In addition, the control circuit uses pulse width modulator (PWM) controller, which ensures invariable and stable current for welding with precise control and high performance.

Features
1. This small, light and portable welding machine has high cost performance and high adaptability to voltage fluctuation.
2. With a high duty cycle of 60%, it can weld continuously.
3. The internal structure is designed with the protection of dust, damp and corrosion, making the machine still has high reliability under harsh environment.
4. Both the arc starting current and arc force current can be adjusted according to welding procedure, so as to ensure deep welding fusion, nice welding shape, as well as high quality welding bead.
5. The VRD function allows the no-load voltage to be retained within the range of 9-24V, which is in compliance with standard safety regulation. This also helps to avoid electric shock.
6. The welding machine is available with an optional remote control device.
