For replacement orders, the connection type, complete torch assembly and required consumable configuration should be verified before purchase.

Key Features of the INWELT P350 MIG Gun

340A CO₂ and 320A Mixed-Gas Ratings

The INWELT P350 is rated at:

• 340A with CO₂ shielding gas

• 320A with mixed shielding gas

• 60% duty cycle

These ratings make the P350 suitable for industrial MIG/MAG welding applications that fall within the specified thermal and electrical operating conditions.

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

Gas-Cooled Construction for Industrial Welding

The P350 uses a gas-cooled, commonly called air-cooled, MIG torch design.

It does not require a separate circulating water-cooling system.

This configuration can simplify equipment installation and maintenance where the welding process does not require a water-cooled torch.

However, a gas-cooled design does not permit unlimited welding time at maximum rated current. The specified duty cycle and operating conditions must be respected.

3 m, 4 m and 5 m Cable Assemblies

INWELT offers three standard cable lengths:

• 3 m

• 4 m

• 5 m

Cable length should be selected according to the distance from the wire feeder to the welding workstation, workpiece size and operator movement requirements.

A shorter cable may simplify routing in compact welding areas. A longer cable provides additional reach but requires proper installation to avoid excessive bends and wire-feeding resistance.

Insulated Handle and Replaceable Torch Components

The P350 uses an insulated nylon handle and a replaceable front-end torch assembly.

The handle houses the trigger mechanism and provides a gripping surface for torch positioning.

Replaceable components include the gas nozzle, contact tip, ceramic diffuser, insulator, torch head and liner.

For industrial purchasing and maintenance, replacement parts should be identified by the corresponding P350 specification and part reference.

Understanding the P350 MIG Torch Duty Cycle

The INWELT P350 is specified at a 60% duty cycle.

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

At a 60% duty cycle, this corresponds to six minutes of welding during a ten-minute period at the applicable rated load.

P350 with CO₂ Shielding Gas

• Rated current: 340A

• Duty cycle: 60%

• Cooling: Gas Cooled

P350 with Mixed Shielding Gas

• Rated current: 320A

• Duty cycle: 60%

• Cooling: Gas Cooled

These ratings should not be interpreted as permission for uninterrupted welding at the specified current.

Actual operating conditions, including ambient temperature, electrical connections, consumable condition and welding duration, may affect torch temperature.

When Is a Higher-Capacity MIG Torch Necessary?

A higher-capacity torch should be considered when the intended welding current or operating duty cycle exceeds the limits of the P350.

Buyers should compare the required welding current, shielding gas, wire diameter, cable configuration and operator requirements before selecting an alternative model.

P350 MIG Torch Cable Lengths and Complete Torch Codes

INWELT lists three complete P350 torch assemblies with different cable lengths.

Complete Torch Code	Description	Cable Length
