Inverter power supplies provide a clocked direct current that is generated by inversion of an intermediate direct current voltage. This principle allows excellent control of the output power and virtually any pulse shapes.
Inverter power supplies today cover almost every application in practice. For most applications, they are the preferred and cheapest alternative for difficult welding processes.
The HF2 High Frequency Inverter precisely controls and monitors electrical AND mechanical weld parameters. Miniature welds are highly sensitive to small heat profile fluctuations in the resistance welding process. Overheating deforms and destroys parts, while underheating results in a weak and unacceptable bond. To achieve consistent, reliable welds of small to micro-miniature parts, heating needs to be precisely controlled. This necessitates superior control of the energy output.
The controls found on the HF25 series closed loop welders address the challenges of micro joining. Miniature welds are highly sensitive to small heat profile fluctuations in the resistance welding process. Overheating deforms and destroys parts, while underheating results in a weak and unacceptable bond. To achieve consistent, reliable welds of small to micro-miniature parts, heating needs to be precisely controlled. This necessitates superior control of the energy output.
Small enough to fit on a bench, the all-new IS-300A 300 Amp inverter spot welder is ideal for customers and integrators who require high output, but have limited production space.
The IS-300A inverter spot welder offers a range of new and improved features including six control modes (primary limit, primary and secondary root mean square (RMS), secondary constant power, secondary voltage control, and fixed pulse) and 0.050 kA - 20 kA of power in 3 ranges. The low current ranges are ideal for small or fine applications.
The IPB5000 inverter resistance welding power supply delivers superior welding control for a wide range of micro-joining applications. When paired with the ITB-780A6 transformer this unit is capable of a maximum output of 6000 Amps, making it ideal for most resistive and conductive welding applications. It operates in constant current, voltage or power feedback modes and is capable of welding in a combo mode (current and voltage) to meet even the most challenging application or process conditions.
The ISQ Series - Inverter Power Supply is designed to be used in combination with mechanical, pneumatical or motorised weld heads. It offers process control monitoring with MG3 and with the AWS3 Active Welding System. The AWS3 integrates the process control of all mechanical and electrical parameters, static and dynamic process monitoring, quality analysis with advanced SPC feature and datalogging.
The new IS series mid-frequency inverter resistance weld controls feature closed-loop current, voltage, and power feedback, fast response times, and a wide range of output power - 0.050-80 kA in 4 ranges. This makes them ideal for small or large, single or mixed part manufacturing.
Packaged in a NEMA enclosure, the new units come as standard with a rotary handle and internal circuit breaker. It has a “triple pulse” weld capability which provides flexible weld profiles and enables three pulses in each cycle. Each weld segment can be programmed with upslope and downslope and may contain up to 19 pulses.
