The high frequency inverter-based welding machines are typically more efficient and provide better control of variable functional parameters than non-inverter welding machines. The IGBTs in an inverter based machine are controlled by a microcontroller, so the electrical characteristics of the welding power can be changed by software in real ...
Perfect Charging is Fronius International's oldest business unit. Fronius has been researching and developing charging technology since it was founded in 1945. The 1990s saw inverter technology applied for the first time to pulsed charging devices for charging vehicle starter batteries. The ACCTIVA series is a starter-battery charging system.
It is used in switching power supplies in high-power applications: variable-frequency drives (VFDs) for motor control in electric cars, trains, variable-speed refrigerators, and air conditioners, as well as lamp ballasts, arc-welding machines, photovoltaic and hybrid inverters, uninterruptible power supply systems (UPS), and induction stoves.
Arc welding power supplies can deliver either direct (DC) or alternating (AC) current to the work, while consumable or non-consumable electrodes are used. The welding area is usually protected by some type of shielding gas (e.g. an inert gas), vapor, or slag. Arc welding processes may be manual, semi-automatic, or fully automated.
In robot welding, mechanized devices both hold the material and perform the weld [72] and at first, spot welding was its most common application, but robotic arc welding increases in popularity as technology advances. Other key areas of research and development include the welding of dissimilar materials (such as steel and aluminum, for example ...
The company manufactures and sells inverter welding machines, engine driven welders and other welder equipment primarily used in construction. [2] Jasic is listed on The Shenzhen Stock Exchange. [1] [2] Jasic was the center of a labor and political conflict in the city of Guangdong, referred to as the Jasic Incident. [4]
