Common Failures
We have observed units where heating output does not reach expected levels. In some cases, the condition begins intermittently and may become more consistent over time. Output current to the coil may plateau below the intended range without fault indicators from the machine.
Repair Approach
Repairs have typically involved replacement of overheated components, including 150 ohm and 470 ohm resistors and the LM361N high-speed differential comparator. Following component replacement, system outputs are recalibrated to ensure correct operation.
Testing & Quality
Post-repair testing includes component and power verification. Our warranty covers the components replaced during the repair process, subject to CSL warranty terms and conditions.
