MK Products 3/8 inch contact tips are replacement consumables for compatible Python, Python LX, Prince XL, Cobra MX with Max cup, and CobraMAX gun assemblies. Match the gun manual, wire diameter and required tip bore before ordering; gun generation and cup configuration matter.
Select the contact tip
The three listed spray-arc tips are 1.57 inches (39.9 mm) long and supplied in packs of 25. The 3/8 inch dimension describes the tip outside diameter, not the wire size. Two options are listed for 3/64 inch wire, so select by the exact part number and bore specified for your application.
| Part number | Wire size | Tip bore | Pack quantity |
|---|---|---|---|
| 621-0391-25 | .035 in (0.9 mm) | .044 in (approximately 1.1 mm) | 25 |
| 621-0392-25 | 3/64 in (1.2 mm) | .053 in (approximately 1.35 mm) | 25 |
| 621-0393-25 | 3/64 in (1.2 mm) | .060 in (approximately 1.5 mm) | 25 |
Confirm gun and wire compatibility
Use the selector to choose an existing part number. If replacing a different tip, provide the gun model, serial or generation, wire material and wire diameter so Justram can check the appropriate replacement. These contact-tip packs do not include the welding gun, cup or liner.
