Thyristor controlled CO₂/MIG/MAG Welding Machines

Best Selling Models with Outstanding Performance and a Wide Application Capability

Good Welding Performance
■ KR2 series uses a special control circuit to achieve low spatter welding in short circuit and spray transfer in CO2/MAG welding.

■ The arc starting circuit allows virtually 100 % arc start success in any operating mode which makes it possible to use this model in both semi-automatic or automatic welding equipment.

■ In simplified unitary mode, the welding current setting on the remote controller automatically determines the corresponding welding voltage.

Simple structure – non-remote control cable design
■ Remote controller connects to the wire feeder directly and the remote controller cable is integrated into the control cable. This reduces the total cable weight and potential for cable damage, which improves mobility.

Outstanding Benefits of the Panasonic Thyristor KR2 System (YD-500KR2)

• Legendary Industrial Durability: The Panasonic Thyristor KR2 architecture utilizes a robust, simplified circuit design. Compared to complex inverter setups, it features a significantly lower breakdown rate, unparalleled tolerance to shop-floor environments, and easier maintenance, ensuring decades of operation.
• Specialized Low-Spatter Control Circuit: Even at a massive 500A output, it ensures precise short-circuit and spray transfer during CO2/MAG operations. The specialized control network delivers clean, high-quality weld beads while minimizing spatter, drastically lowering post-weld cleanup costs.
• Near 100% Arc-Starting Success Rate: Featuring an optimized arc-ignition circuit, it achieves virtually 100% successful arc strikes in any technical mode. This rapid, consistent ignition makes it perfectly suited for high-speed manual operations as well as seamless integration with automatic welding systems and robotic cells.
• Unitary Control Mode & Lightweight Cable Layout: Operators can easily adjust welding parameters using the simplified unitary mode, where changing the current automatically configures the ideal voltage. Furthermore, the non-remote control design routes the remote lines directly into the wire feeder cable, shedding unnecessary weight and safeguarding cables from workshop damage.
