Contact tips

  • Original Kemppi contact tips ensure optimized welding current transfer to filler wire. Kemppi contact tips are available for all wire materials in most common wire sizes from 0.6mm up to 1.6mm. Larger diameters up to 3.2mm are also available.

Contact tip adapters

  • Copper or brass contact tip adapters are available for all genuine Kemppi contact tips.

Wire liners

  • Kemppi wire liners are strong, durable and efficient, designed to suit specific filler wire materials and applications. Most of Kemppi’s wire liners are color-coded the same way as the feed rolls in Kemppi wire feeders. This helps to select suitable material for your use. Kemppi liners support the filler wire and ensure its reliable delivery to the welding arc.

DL Chili Liner

  • Kemppi’s patented teflon liner DL Chili is a two-component plastic liner type that represents the latest solution for reliable feeding of aluminum, stainless steel, acid-resistant and solid steel filler wires. DL Chili technology reduces the surface friction between the filler wire and the liner wall, reducing drag by up to six times compared to traditional plastic.

Wire guide tubes

  • Wire guide tube guides and focuses filler wire to the gun’s wire liner when the wire moves from the wire feeder to the gun.

Neck wire liners

  • A short piece of wire liner inside gun neck, used in gas-cooled multi-neck MIG welding guns.
