Purpose-built acetylene tip

The MW203 is a Smith Equipment acetylene welding tip sized for 5/64 in maximum plate thickness. It belongs to the MW200 series and fits MW200-compatible torches including the CW5A, MW5A and WH100 models. The tip delivers a soft flame at up to 10 psi acetylene pressure.

Replacing worn MW200 tips

Swap this tip in when an existing MW200-series tip shows erosion or inconsistent flow that degrades bead quality. The jump is worth it when drill size 67 and the 3.2 scfh fuel and oxygen flow ratings match the original specification for the torch in use.

Suited for light-gauge acetylene work

Welders running acetylene on thin sheet up to 5/64 in will find the soft flame and 7.5 in length practical. Buyers who need a different drill size, higher flow capacity or a fuel type other than acetylene should look at other tip series.

Questions about this item

What torch series does the MW203 tip fit?

The tip is compatible with the MW200 torch series and manufacturer part numbers CW5A, MW5A and WH100.

How do I install the tip correctly and what step is often missed?

Thread the tip onto the MW200 series torch by hand, then tighten with a wrench; the step often missed is setting the acetylene regulator to no more than 10 psi before lighting.

When should the tip be replaced and what wears out?

Replace the tip when the orifice at drill size 67 shows erosion or the soft flame becomes irregular, typically after extended use at the rated 3.2 scfh flow rates.
