Product Overview: The 9690 Arc Length Controller by Jetline Engineering (model ALC-401-6) is a programmable control system used in automated welding equipment to maintain consistent arc voltage and electrode-to-workpiece distance. It monitors real-time arc voltage, compares it to programmed setpoints, and drives motor actuators to adjust electrode position accordingly. The controller features a digital LCD display, keypad interface, and multiple I/O connections for integration with welding power supplies, motors, and external sensors. It includes programmable parameters for arc voltage setpoints, start delays, touch/retract sequences, and jog controls. Internal components include a microcontroller, non-volatile SRAM for parameter storage, power supply circuits, relay outputs, and rotary encoder for manual adjustment. Common applications include submerged arc welding systems, automated pipe welding, and precision metal fabrication operations requiring stable arc control.

Manufacturer Part Number: ALC-401-6
Also Known As(AKA): 9690
Common Failures
Frequent issues include memory-related problems involving non-volatile SRAM components, which may result in settings being lost or requiring resets to factory defaults. Other problems involve components such as incremental encoders that may become physically damaged during handling or shipment. Customers have reported unstable voltage control and unreliable touch or retract functions, which can sometimes be related to external setup or mechanical connections.
Repair Approach
Repairs may involve replacing defective memory components and restoring units to factory settings. For encoders and other physical components, replacements and securing connections are typical solutions. In cases of corrupted parameters or memory issues, resetting and testing memory retention are standard practices. Connections found to be loose or damaged are repaired or reinforced as needed.
Testing & Quality
Testing procedures are conducted to verify functionality after repairs. Specific checks are performed to confirm that units retain settings and operate correctly after periods without power. Units are tested to ensure input/output operations function as expected and meet specified parameters.
