Helvi Compact 305hf Inverter (tig & Mma)
The HELVI COMPACT 305HF is a robust, high-performance inverter designed for both TIG and MMA welding applications. Built to handle a variety of demanding environments, this machine excels in both industrial and field settings, thanks to its stable operation even when connected to unstable power sources like generators or long extension cables. Its an ideal choice for professionals in fabrication, shipbuilding, automotive repair, and structural welding.
At the core of the COMPACT 305HF is advanced microprocessor control, which ensures precise arc performance and automatic adjustment based on the type of electrode used. For TIG welding, it features both high-frequency (HF) and lift arc ignition, offering smooth starts and clean welds. The unit supports multiple welding modes, including 2-stroke, 4-stroke, as well as pulsated variations of each, providing greater flexibility for different welding techniques and materials.
In MMA mode, welders can fine-tune critical settings like Arc Force and Hot Start, allowing for better control, especially when working with difficult electrodes. Safety is also a key priority, with the inclusion of a Voltage Reduction Device (VRD) that minimizes open circuit voltage when the machine is idleideal for operating in high-risk environments. This feature can be enabled or disabled depending on the application.
The COMPACT 305HF is also designed for ease of use. A large, digital display provides real-time feedback on welding current and voltage, making it simple to monitor and adjust settings on the fly. For added convenience, the machine is compatible with remote controls and foot pedals, giving the operator maximum control during critical welding tasks.
With a wide output range of 5 to 300A in TIG mode and 5 to 270A in MMA mode, and a high duty cycle of 50% at 300A (TIG), the COMPACT 305HF delivers consistent performance during long, intensive jobs. Its compact design and 23 kg weight make it relatively portable for its class, while the durable construction ensures longevity under tough conditions.
Although the HELVI COMPACT 305HF has been discontinued, it remains a respected and widely used machine in the field.
