Multiquip MQ37289 Contact Tip 1/16" Medium Standard MT400CCEHD

The Multiquip MQ37289 Contact Tip 1/16" Medium Standard MT400CCEHD is a genuine OEM contact tip designed for the MT400CCEHD welder. Sourced directly from Multiquip, this part meets the original equipment specifications for consistent arc performance and wire feed accuracy. It is a direct replacement for the MT400CCEHD, ensuring a correct, hassle-free installation with no guesswork on fitment.

Key Features

• Genuine OEM Conductivity Rating — Manufactured to the original copper alloy specification for the MT400CCEHD, delivering consistent current transfer at the weld point.
• Correct 1/16" Bore Diameter — Sized precisely for 1/16" wire, ensuring smooth, unobstructed wire feed and stable arc initiation on every pass.
• Medium Standard Profile — The medium standard geometry fits the MT400CCEHD MIG gun neck without modification, threading in like the original.
• Fits MT400CCEHD — Verified OEM fitment for the Multiquip MT400CCEHD welder; use model code MT400CCEHD to confirm compatibility before ordering.
• Arc Stability and Weld Quality — A worn or eroded contact tip causes erratic arc behavior, spatter, and poor bead quality; replacing with this part restores clean, predictable welds.

A contact tip is the small consumable threaded into the end of a MIG gun neck through which the welding wire passes and receives its electrical charge. As current flows through the tip and into the wire, it creates the arc that melts and fuses the base metal. Because the tip is in direct contact with the wire and exposed to intense heat and spatter, it erodes over time — enlarging the bore, causing poor electrical contact, and leading to an unstable, wandering arc. Replacing the contact tip with the correct this part restores proper wire-to-tip contact and consistent arc performance on the MT400CCEHD.
