LM weld control

Turn classic welders into smart machines. Control voltage, arc force, and AC TIG from your iPhone with real-time voice control and zero-lag BLE.

LM Weld Control

LM Weld Control is a professional mobile control and management system designed for engine-driven welding machines such as the Lincoln SA-200 and similar generator-based welders.

The app allows users to wirelessly monitor, adjust, and manage welding equipment through a secure Bluetooth connection to compatible control hardware, bringing modern digital control to classic industrial machines.

Key Features

• Wireless control of welding voltage, amperage, and operating modes • DC Stick, DC Wire, DC Advanced, and AC welding support • True digital arc-force and hot-start control • Real-time voice-activated welding adjustments with ultra-low latency • Machine profiles and saved welding configurations • Secure Bluetooth Low Energy (BLE) communication • Live feedback from connected control hardware • Built-in marketplace for machines, parts, and services • Repair shop and welding supply store locator • In-app messaging between buyers and sellers • Designed for professional and industrial use

Advanced Welding Control

LM Weld Control provides true arc-force and hot-start control, allowing the welding arc to remain stable during difficult starts, rod sticking, and changing load conditions.

Voice control enables hands-free adjustment of voltage, amperage, and welding modes with near-instant response, allowing operators to fine-tune settings without stopping work.

DC-to-AC TIG Capability

When paired with compatible control hardware, LM Weld Control supports conversion of DC generator output into controlled AC waveforms, enabling AC TIG welding for aluminum and other specialized applications.

This allows legacy engine-driven welders to support modern TIG welding modes that were previously unavailable on these machines.

Built for the Future

LM Weld Control is built as a continuously evolving platform. The app and control firmware support future feature updates, new welding modes, improved arc shaping, and advanced monitoring without replacing hardware.

Maps & Location

Maps are used to display business locations such as repair shops and welding supply stores. Private marketplace listings do not display precise map locations. Navigation to stores and shops is handled through Apple Maps.

Who It’s For

LM Weld Control is built for: • Professional welders • Repair shops • Equipment owners • Fleet managers • Welding supply dealers

It modernizes legacy engine-driven welders with wireless control, intelligent arc management, AC TIG capability, and integrated service tools.
