Welding

Welding is the foundational process that creates the strong, permanent, and reliable metal bonds required for equipment that endures constant stress, heavy loads, and repetitive motion.

Modern welding machines often use inverter technology, making them lighter, more compact, energy-efficient, and providing smoother, more precise arc control compared to older transformer models.

Current sensors are key components in inverter welding machines, measuring and monitoring the current flowing through the circuit. They ensure optimal performance by accurately measuring current levels during welding operations. This real-time monitoring maintains weld quality and prevents problems such as overheating.

Typical applications

TIG welding machines
MIG/MAG welding machines
MMA welding machines
Plasma welding machines
Plasma cutting
Inductive heating

Precision Current Sensing for Advanced Welding Inverters

In the demanding environment of modern inverter welding machines, precise current feedback is essential for stable arc control and equipment longevity. Our comprehensive portfolio, featuring the K03, K18, LF01, LF03, NxxxP, and Y06 series, offers tailored solutions based on robust Hall Effect technology.

Designed to withstand high thermal stress and electromagnetic interference, these sensors bridge the gap between power control and performance. Whether utilizing the cost-effective reliability of Open Loop designs (K/N/Y series) or the superior linearity and microsecond-level response of Closed Loop sensors (LF series), these components ensure accurate real-time monitoring of DC and pulsed currents.

By providing clean signal inputs to the controller, they play a critical role in optimizing the PWM control loop, stabilizing the welding arc, and providing rapid short-circuit protection for power semiconductors (IGBTs/MOSFETs), ensuring your welding equipment delivers consistent, high-quality results.
