Tweco Gas Diffuser WM250 Pack of Five
The Tweco 15201141 gas diffuser fits WM250 MIG guns and Classic No. 2, No. 3 and No. 4 series torches. It is sold as a pack of five replacements for welding shops and maintenance teams that run these gun models.
WS52FN Diffuser Number Ensures Correct Fit
The WS52FN part number matches the original equipment specification so gas flow and tip seating stay consistent. Buyers who need a different diffuser number or a gun series not listed will not be able to use this pack.
Verify Gun Model and Diffuser Number Before Ordering
Check that your MIG gun is a WM250, WM400 or Classic No. 2, No. 3 or No. 4 and that the current diffuser is stamped WS52FN. If the gun uses another series or a different diffuser code this pack will not fit.

Questions about this item
When should I replace the WS52FN gas diffuser on my Tweco WM250 gun?
Replace the WS52FN diffuser when gas coverage becomes inconsistent or the tip seats poorly, typically after heavy daily use or if spatter blocks the gas ports.
What fails first on the WS52FN diffuser during long welding runs?
The ceramic insulator cracks from thermal cycling before the brass body wears, cutting shielding gas flow and causing porosity.
How hot does the WS52FN diffuser get during all-day welding at 250 amps?
The diffuser runs hot enough to burn bare skin; let it cool before removal and expect shorter life if run continuously near the gun's 250-amp rating.
