Key Features of the INWELT PSF305 MIG Gun

290A CO₂ and 260A Mixed-Gas Ratings

The standard INWELT PSF305 is listed with the following ratings:

• 290A with CO₂ shielding gas

• 260A with mixed shielding gas

• 60% duty cycle

The specified ratings help buyers evaluate the welding gun according to their welding process and operating requirements.

The intended welding current should be selected according to the welding wire, shielding gas, welding procedure and expected arc-on time.

Gas-Cooled Swan Neck Design

The PSF305 uses a gas-cooled swan neck welding gun configuration.

The torch does not require a separate circulating water-cooling circuit.

Its curved front-end design allows the operator to position the contact tip and gas nozzle at the required working angle during manual MIG/MAG welding.

The correct welding current and operating duty cycle must be observed to prevent excessive torch heating.

Euro Central Connector

The PSF305 is supplied in a Euro central connector configuration according to the standard INWELT product listing.

The connector forms the interface between the welding torch and a compatible wire feeder.

It combines the required mechanical attachment and connections for welding current, wire feeding, shielding gas and trigger control.

Actual compatibility depends on the corresponding machine connection and pin configuration.

3 m, 4 m and 5 m Cable Assemblies

INWELT supplies PSF305 welding guns in three standard cable lengths:

• 3 m

• 4 m

• 5 m

The appropriate cable length depends on the welding workstation, workpiece size and distance between the operator and wire feeder.

A shorter cable may simplify cable routing in compact welding areas. A longer cable offers greater reach but requires appropriate installation to reduce unnecessary bending and feeding resistance.

Replaceable Front-End Components

The PSF305 includes replaceable components for welding current transfer, gas distribution and wire feeding.

These components include the contact tip, gas nozzle, gas diffuser, torch head and wire liner.

Using the correct replacement parts helps maintain the intended front-end configuration and simplifies maintenance.

Understanding the PSF305 Duty Cycle

The INWELT PSF305 is specified at a 60% duty cycle.

Duty cycle describes the percentage of a standard ten-minute operating period during which a welding torch can operate at the specified rated current under the relevant test conditions.

At a 60% duty cycle, the welding gun can operate for six minutes during a ten-minute period at the applicable rated load.

PSF305 with CO₂ Shielding Gas

• Rated current: 290A

• Duty cycle: 60%

• Cooling: Gas Cooled

PSF305 with Mixed Shielding Gas

• Rated current: 260A

• Duty cycle: 60%

• Cooling: Gas Cooled

The current rating is not identical for every shielding-gas mixture.

Actual operating conditions, including ambient temperature, electrical connections, cable condition and welding duration, should also be considered.

What Happens If the PSF305 Duty Cycle Is Exceeded?

Operating beyond the specified duty cycle may cause excessive heating of the welding gun and its components.

Possible symptoms include:

• Excessive torch neck temperature

• Increased contact-tip wear

• Hot cable or electrical connections

• Damage to front-end components

• Unstable welding performance

If overheating occurs, stop welding and allow the equipment to cool before inspection.
