250 A air-cooled MIG gun

The Tweco WM250-15-4045 is a new air-cooled MIG gun rated at 250 A with a 60 percent duty cycle. It handles solid and aluminium wire up to .045 in diameter and comes with a 15 ft cable. The fixed neck is angled at 60 degrees and uses WS14 series tips for GMAW processes.

Tweco-compatible rear connection

The gun connects to machines that accept a Tweco-compatible rear fitting, so no adapter is required for those feeders. Its curved handle and standard trigger give a familiar grip for extended welding sessions. Air cooling removes the need for a water cooler, hoses or coolant, simplifying the setup and reducing floor clutter.

Suited for light fabrication and maintenance

This gun suits welders running CO2 shielding gas on thin-to-medium plate where a 250 A class tool matches the job. Shops that need higher amperage, a longer cable, a rotatable neck or water cooling for continuous high-duty work should look at larger or liquid-cooled models instead.

Questions about this item

How long can the WM250-15-4045 run continuously at its 250 A rating before it needs to cool down?

The gun carries a 60 percent duty cycle at 250 A, so it can weld for six minutes out of every ten before a cool-down period is required.

Does the air-cooled design stay quiet and cool enough for all-day production work?

Air cooling relies on ambient airflow rather than fans, so the handle stays comfortable during normal shifts, but sustained high-amperage runs will warm the cable and neck.

What wire feeder connection does the gun need to plug into?

It uses a Tweco-compatible rear connection, so the feeder must accept that standard plug for the gun to work.
