The new Typhoon 230 begins by setting a new class standard with 70% duty cycle at maximum output. It also has new large 5.1" HD LCD screen with crystal-clear resolution and brightness. The new functions of Amplitude control in AC and split positive and negative wave form control offer astounding advances of tungsten life, arc quality and stability over older wave form technology. The Typhoon has five AC wave forms, Advanced Square, Soft Square, Triangular, Sine and Trapezoidal wave forms, that are available to offer the maximum level of puddle and bead control while welding Aluminum. With expanded memory option up to 30 programs and the ability to lock down programmed settings to prevent tampering, the unit helps customers maintain quality control levels where multiple users are present or where a WPS is in place. Other performance-driven features such as DC pulse wave form shaping and a new type of solid state HV/HF starting for TIG secures the Typhoon 230's place as a premier, next level TIG welder in all metals categories. It is also a top-level stick welder with features such as AC and DC stick output, with adjustable AC balance and Frequency, and excellent 6010 performance. It also has arc force control (dig) and hot start adjustment to combine to run E7018 as smooth as any welder out there. The unit has up to 200Amp Stick output at 70% duty cycle which means this unit is perfect for running root, fill and cap passes. The Typhoon also has other features that aren't readily apparent but found on the inside such as high Power Factor Correction (PFC) which allows the unit to be more "forgiving" on generator power sources and consume less power overall. The unit's ability to operate on 120V or 240V improves usefulness where the power availability may be unknown on a job site. New fan and cooler control technology allows the fans and water cooler to run only when needed.
