CSL Part Number: 75921
Product Overview: The ALC201 Arc Length Control is a welding automation controller manufactured by Jetline Engineering. It monitors arc voltage during automated welding processes and adjusts the torch-to-workpiece distance by controlling vertical positioning motors to maintain consistent arc length. The device features RS voltage sensing inputs, analog voltage display, and motor drive outputs for vertical head movement. It is typically used in submerged arc welding systems, automatic welding carriages, and column-and-boom welding manipulators where maintaining stable arc voltage is critical for weld quality and penetration consistency.

Repair your ALC201 to maintain a constant arc gap under all conditions.
Common Failures
Several common issues have been identified with this product. One frequent problem is the power indicator light burning out, which prevents visual confirmation of power status. Another noted issue involves intermittent connections caused by oxidation on tin-plated connector contacts. In some cases, the RS function fails to sense voltage, leading to operational issues.
Repair Approach
Repairs may include replacing the burned-out power indicator with a green LED and applying a dropping resistor to ensure compatibility. Connector issues can be addressed by seating connectors properly, applying a contact cleaner to mitigate oxidation, and securing connector halves with a tie wrap. Additionally, routine maintenance may be performed, including tightening the fuse holder and clearing debris around voltage regulator areas.
Testing & Quality
Repairs are followed by comprehensive diagnostic testing using established procedures. Both voltage regulators are confirmed to operate at appropriate levels, and post-repair testing with a DC motor confirms the expected performance of the unit. Testing ensures that units meet operational standards before being returned to service.
