Tornado™ARC400i LCD | heavy duty, fan cooled, IGBT based inverter controlled power sources meant for MMA / TIG (scratch-start) welding.
Robust control panel protected against accidental impact. Extreme power to weight ratio in a most compact format. Rugged composite casing for durability in the roughest environments. For professional MMA welding with electrodes up to 6mm with a high duty cycle of 400 A at 80%. Ideal for operation in high ambient temperatures. The machine automatically provides operators with the optimal start and stop parameters based on the set welding current. A booster circuit provides additional voltage for superior cellulosic arc starts and welding performance.
MMA Welding
A wide current range and powerful welding performance make the Tornado™DCArc machines suitable for a wide range of applications and electrode types such as:
•General purpose
•Stainless steel
•Cellulosic
•Low-hydrogen
Hot Start
To improve the arc striking with themost difficult electrodes.
ARC FORCE
To choose the best are dynamic characteristics.
TIG Welding
The Tornado™DC Arc machines are capable of performing TIG welding with precise current control. All you need is an optional TIG-torch with a gas valve, a gas regulator and a cylinder of gas. You can weld mild steel or stainless steel material with or without filler material.
VRD is short for Voltage Reduction Device
VRD reduces the welding power source’s open circuit voltage (OCV). OCV is the voltage measured across the terminals when not welding. VRD is a device that reduces open-circuit voltage (OCV) to a safe value until welding commences.
