The hot wire GTAW (TIG) process is used in industries requiring high quality, high productivity welding. Although the GTAW process has a much lower deposition rate than GMAW (MIG), the quality is generally superior. When hot wire technology is used in conjunction with GTAW, especially in down hand welding on plate or on larger diameter pipe, deposition rates can approach that of MIG.
Hot wire GTAWnarrow groove welding has been used extensively for the welding of nickel-based alloys, a wide range of steel alloys as well as reactive metals such as titanium. Hot wire GTAW equipment is finding increasing uses in industry applications as varied as valve manufacture, oil and gas industry components,and components used in nuclear power generation.
Hot Wire TIG helps pre heat the filler wire before entering the welding pool. This helps in the deposition rate.
The output of sigmaweld welding inverters are constant even if there is a power fluctuation int he mains of up to +- 15%. The power source equally works well on generator sets with balanced load. The output current does not even drop at 100 meters of copper cable length.
SigmaWeld inverters are designed for safety of both operator and machines. It has inbuilt protections for over voltage, undervoltage, output short, thermal overload and IGBT peak current locking. This ensures longer life of equipment and our inbuilt voltage reduction circuit which ensures OCV as low as 24 volts or below when not welding keeps operators safe.
