三葉電熔社 List of Products and Services

The CO2/MAG welding machine Digital Auto DM500 is a fully digital welding power source. Thanks to digital electronic reactor control, it reduces spatter compared to XD. It creates optimal current waveforms from low to high current ranges. Digital electronic reactor control smooths the waveform to prevent the current from becoming too high at the moment of re-arc during the welding phenomenon of short circuit and arc repetition, which can cause spatter. For more details, please contact us or refer to the catalog.

The CO2/MAG welding machine Dyna Auto XD500II is a fully redesigned model of the basic version, boasting exceptional operability and robustness. Equipped with a new high-performance microcontroller, it has improved processing speed and memory capacity comparable to digital inverter welding machines, achieving expanded welding modes and enhanced starting performance. It is resistant to fluctuations in input voltage and frequency, ensuring consistently stable welding quality. By attaching the optional "brake unit" to the feeding device, it effectively suppresses wire feeding at the end of welding, making it effective for tack welding during extensions. The standard inclusion of a simple drip-proof sheet to protect the panel operation components has significantly improved robustness and maintenance.

The CO2/MAG welding machine Digital Inverter DL350II is equipped with CBT (Controlled Bridge Transfer) control, which is a superior control method compared to the DR series, further reducing the occurrence of spatter. It tends to have shallower penetration than DM, making it ideal for thin plate welding. CBT is a control method that predicts the occurrence of the arc in advance and instantaneously suppresses the current to facilitate smooth droplet transfer. The new welding mode "AC Short Arc Welding Method" significantly improves the welding quality of thin plates. The new arc start method "CP Start Control" achieves stable arc starting. For more details, please contact us or refer to the catalog.

The CO2/MAG welding machine Digital Auto DR350 features a higher-level control method than the DM series, equipped with DAC II (Dynamic Arc Control II) control, which further suppresses the generation of spatter. DAC II control cuts the peak current value at the moment of arc generation, allowing for smooth droplet transfer. It achieves a higher level of welding quality with digital inverter control. Conditions for high-speed welding can be easily set with the push of a button, significantly improving arc starting performance. For more details, please contact us or refer to the catalog.

• Welding Machine

The CO2/MAG welding machine Inverter Auto CPV600 optimally controls the welding current, significantly improving arc stability and arc starting performance. With optimal current waveform control for wire diameter and welding current, the appropriate range of welding voltage is expanded, allowing for stable arcs from low to high currents. It comes standard with a direct-reading remote control, enabling two types of settings for welding conditions: "centralized adjustment," which automatically adjusts to the optimal arc power by simply setting the operating current, and "individual adjustment," which allows for separate settings of current and voltage.

The CMT (Cold Metal Transfer) welding method involves the wire advancing while producing an arc (hot process) and simultaneously short-circuiting, causing the arc to extinguish (cold process). The wire is then forcibly cut and retracted. By performing this cycle at high speed in 14 ms, it significantly suppresses heat input and greatly reduces the explosive phenomenon of the molten pool, resulting in minimal spatter generation. This method is particularly effective for ultra-thin sheets of less than 1 mm. Due to its similarity to brazing, it is also an effective method for welding ultra-thin sheets with gaps or when there are concerns about melting. For more details, please contact us.
