Product description

STAUNCH Welding Machine

Function & Features:

Welding Manner: Electrode Welding

Scope of Application:  Shipbuilding, Power Supply, installation of large steel structure, Heavy Industrial Production. Maintenance. Civil Steel Structure, etc.

Applicable Materials: Acid /Alkalescency Electrode, Stainless Steel Electrodes, Cast Iron Electrode, Cellulose Covered Electrode, Heat-resistant Steel

Electrode, etc, for welding low, carbon Steel, Medium Carbon Steel, and Alloy Steel.

Precise Control System:

1- Adopted advanced half-bridge inverter technology of single-tube IGBT.

2- Current-mode pulse width modulator )PWM) the controller provides invariable and stable current with precise control and excellent performance.

Advanced Inverter Technology:

1- Small, light, portable, and cost-effective

2-Voltage-pressure compensation with a strong capacity of anti-power fluctuation.

3-High duty cycle maintains the welding continuously

4- three protection( anti-dust, damp proof, anti-corrosion) of the internal structure increased the machine’s reliability under harsh environment.

Excellent Welding Performance:

1- Strong arc starting current adjustment function which can adjust arc starting current according to welding procedure,

greatly improved the success rate of arc starting.

2- Strong arc force current adjustment function guarantees the stable welding bead formation, which is also convenient to

the adjustment of fusion depth.Strong adaptability of welding power to the welding procedures.

3- Deep welding fusion, nice welding shape with high quality of welding bead Perfect Protection System:  Automatic protection on over-current

and over-heating ensured the machine’s safety, durability, and reliability.

VRD function: No-load voltage is retained to 9-24V, which follows the standard safety regulation and against electric shock.
