63-1135 - ATTC Lightning Style .035 HD Taper Lock Contact Tip (10-Pack)

Engineered for Conductivity and Thermal Efficiency

The American Torch Tip (ATTC) 63-1135 Contact Tip is a premium consumable designed specifically for the Lightning series of MIG guns. Unlike traditional threaded contact tips, this heavy-duty component utilizes a specialized Taper Lock design. This engineering choice is critical for high-performance industrial welding environments. By relying on a tapered wedge fit rather than threads, the tip establishes a significantly larger surface area of contact with the gas diffuser (specifically the 63-3103 model). This maximized contact area ensures superior electrical transfer efficiency, reducing resistance and the associated heat buildup that often leads to premature failure in standard tips.

Thermal management is further enhanced by the heavy-duty copper alloy construction, which provides greater thermal mass to dissipate heat away from the wire interface. The absence of threads also eliminates the common issue of seizing caused by thermal expansion and spatter accumulation, ensuring that maintenance intervals are dictated by wear rather than mechanical lock-up. For automated or high-duty-cycle manual applications using .035" (0.9mm) wire, the 63-1135 offers a robust solution that maintains arc stability through consistent current transfer and precise bore tolerances.

This OEM part guarantees dimensional accuracy and material quality consistent with ATTC's manufacturing standards. The precision-drilled bore minimizes micro-arcing inside the tip, a common cause of burn-backs and erratic feeding. When paired with the correct Lightning gun setup, these tips facilitate a stable welding parameter window, essential for meeting rigorous code requirements in fabrication.
