COMMON ISSUES AND SYMPTOMS

What the product may be indicating

These are general diagnostic paths for this product category. Error-code numbers differ between brands, markets and revisions, so EgoFile shows a code only after it is confirmed in the exact official manual.

Source policySafe checks are maintained by EgoFile and linked to the official source record. No third-party manual text is copied.
01NO ARC

Arc will not start

High priority

What it means: Earth connection, polarity, consumable or output selection may be incorrect.

First safe check: Isolate power, inspect accessible leads and confirm process and polarity.

Stop condition: Do not use damaged insulation, wet equipment or an unsecured gas system.

02UNSTABLE

Arc or wire feed is unstable

Medium priority

What it means: Parameters, consumables, gas flow, liner or material preparation may be unsuitable.

First safe check: Stop and verify the documented setup, consumable path and clean work connection.

Stop condition: Isolate before opening a feed compartment or changing internal parts.

03THERMAL

Thermal protection is active

High priority

What it means: The duty cycle, cooling path or ambient conditions exceeded the machine limit.

First safe check: Leave power and fan state exactly as specified for the full cooling period.

Stop condition: Request service if protection returns at a light load.

04GAS

Shielding-gas leak or poor coverage

High priority

What it means: A connection, hose, regulator, flow or wind may disrupt shielding.

First safe check: Close the cylinder, ventilate and inspect approved external connections.

Stop condition: Do not operate a damaged regulator or search for leaks with a flame.

QUICK CHECKS

Three additional checks

Use these checks when no error code is displayed.

Arc will not start

Check earth connection, polarity, consumable and output selection.

Arc is unstable

Verify material preparation, gas flow, wire feed and parameters.

Thermal warning

Stop and allow the complete specified cooling period.
