55V No-Load Voltage

The ARC250ST has a listed no-load voltage of 55V.

No-load voltage is present when the welding machine is switched on, but no welding arc is active. Avoid touching exposed output terminals, electrodes or conductive welding components while the machine is connected to electricity.

Rated Output Voltage Not Stated

The supplied specification does not provide a rated output-voltage value.

Recommended catalogue wording:

Rated Output Voltage: Not Stated

Add the value only after checking the physical machine rating label or manufacturer documentation.

Listed 60% Duty Cycle

The welding machine has a listed duty cycle of 60%.

Duty cycle indicates how long the machine can operate during a defined test period before cooling is required.

The supplied information does not identify:

• The welding current used during testing
• The ambient test temperature
• The testing standard
• The required cooling time

Recommended wording:

Listed Duty Cycle: 60%

Do not claim continuous welding at 200A or 250A unless a current-specific duty-cycle chart confirms it.

Listed 80% Efficiency

The ARC250ST has a listed efficiency of 80%.

This value can be included in the technical specification section. Avoid direct efficiency comparisons unless the competing welding machines were tested under equivalent standards and operating conditions.

0.73 Power Factor

The supplied specification lists a power factor of 0.73.

This is useful information for professional buyers and electrical-installation planning.
