Features:
- Repeatable and precise resistance welding/micro welding for high productivity.
- Fine waveform control via « Freestyle Profiling » and multi-level programming
- Freely selectable frequency (2, 4, or 5 kHz, which can be stored in the welding programme)
- Multiple control modes: constant current, constant voltage or constant power.
- Real-time monitoring of welding processes.
- Automatic data recording
- High Performance Monitor for visualising and documenting individual parameters and curves.
- « 4-in-1 » multi-transformer system to increase productivity
- Data sheet download
AVIO resistance welding units MCW-700/MCW-750
Transistor-controlled welding generator for exacting requirements.
These devices are designed for high-precision welding tasks with extremely sensitive weld metals, such as fine wires or micro components.
Features:
- Repeatable and highly precise resistance welding/micro welding
- High throughput due to extremely fast pulse sequence: 5 pulses/second
- Control options: Constant current, constant voltage or constant power
- Pre-welding with test function
- Real-time monitoring of welding processes.
- Simultaneous graphical display of the current, voltage and power curves
- Automatic data recording
AVIO resistance welding unit NRW-DC150
The NRW-DC150 capacitive discharge welder is designed for resistance welding applications in the fields of battery/battery pack production, aluminium and copper processing.
Features:
- Especially well-suited to materials such as aluminium and copper
- Dual pulse welding function prevents sparks and improves welding quality
- Short and concentrated energy burst prevents deformation and burning
- Adjustable power output (modes: very short, short, medium, long)
- The « very short » mode achieves a power output of up to 200 W x s (5.5 kA, 2.1 ms)
- Short charging cycles improve productivity (75 W x s; 120 welding pulses per minute).
AVIO resistance welding heads
AVIO resistance welding heads and/or micro welding heads are characterised by a compact and precise design.
The different designs include opposed, parallel and parallel/series electrodes.
Depending on the area of application and type, the system heads may be manually or pneumatically operated or motorised, within a pressure range of 0.50 to 1800 N.
Either a compact, handheld digital force gauge (FG-400) or a real-time force monitor with colour display (QC-100 or QC-200) can be used to monitor the displacement.
AVIO electrodes
We offer a wide range of different standard welding electrodes for resistance welding or micro welding processes.
The electrode shape and material should be chosen based on the welding metal. Electrodes in other, customer-specific dimensions and shapes are also available.
We will be happy to assist you in selecting the right electrode and defining bespoke solutions. Contact our experts for advice and we will work together to find the optimal solution for your application.
