How smart welding delivers gas savings through AI sensing and closed-loop gas control

The goal of smart welding is to add digital intelligence to every industrial welder — clamped onto any brand, installed non-invasively in about 15 minutes, at near-zero cost: the gas it saves quickly earns the hardware back. It is proven on BMW, Honda and 100+ production lines, with 70+ invention patents.

The value one welder can create, every year:

SUXIN builds this into a single loop — sense → AI reads → close the loop — three steps in one place:

• ▪Sense: read welding current in real time, and capture voltage, wire feed, gas flow, temperature and pressure alongside it, at up to 1 MHz sampling.
• ▪AI reads: match the correct process and turn the signals into quality, cost, efficiency and utilization (OEE).
• ▪Close the loop: adjust shielding gas in real time by current, held between the process limits — no arc-start overshoot, no end-of-weld spill, fully automatic.

Gas saving happens at the “close the loop” step. The chart above compares passive supply with SUXIN active closed loop; the shaded area is exactly the waste removed — about 25% welding gas saving per machine, measured and verifiable, and the hardware achieves it on its own.
