General Description
This WeldMax™ series welding machine, designed for welding low-carbon steel, alloy steel, and stainless steel,
uses advanced inverter technology, which allows us manufacture a unit that can also employ a Plasma Cutter.
By employing high-power MOSFETS and PWM technology, it converts DC voltage to high frequency AC
voltage. Subsequently, voltage is transformed and rectified, resulting in a small main transformer and a light-
weight inverter welder, which increases welding performance rates by 30%. High frequency oscillation,
enabling high frequency DC output, is used in the arc-starting system. This machine provides stable output, and
reliable, completely portable, efficient, and low noise generation, while welding or cutting.
The WeldMax™ series has three different functions: TIG, Arc, and plasma cutting. During ARC or TIG welding,
this equipment provides stable output with no arc-length variations. During plasma cutting, the arc, being driven
by highly compressed air, sees a rapid temperature rise up to 10,000 to 15,000 degrees, and becomes highly
ionized. Consequently, it produces the powerful plasma arc for cutting. Plasma cutting saves energy, is efficient,
and creates smooth, high-speed cuts. These machines weld and cut carbon steel, stainless steel, alloy steel, as well
as copper and other nonferrous metals. They are small, highly efficient, energy saving, stable in output, and
reliable. Their ratio of input voltage to output voltage approaches 85 percent.
