Item Details
- The ITW Bernard 4986 is a MIG gun adapter kit with a control plug designed to interface Miller or Bernard welding guns with Lincoln Electric LN-7 and LN-7 GMA semiautomatic wire feeders. It serves as a mechanical and electrical bridge, allowing the use of Miller-style gun configurations on Lincoln wire feeding platforms.
Features
- Cross-brand hardware bridge for Miller/Bernard guns and Lincoln LN-7 feeders
- Integrated internal O-ring sealed gas pass-through for shielding gas delivery
- Micro-polished internal bore to minimize friction coefficients
- Dedicated control plug matching LN-7 trigger circuits
- Dielectric insulation sleeve to prevent high-amperage shorting to feeder chassis
- High-conductivity brass body for structural heat dispersal
- Plug-and-play control integration without manual wire splicing or crimping
