Pro-source 14-45 Mig Welder Contact Tip 0.045 in Wire Dia

Product Description

The PRO-SOURCE 14-45 is a MIG welder contact tip designed for use with 0.045 inch wire diameter. The contact tip is the final point of electrical transfer between the welding machine and the wire electrode, threading current through the tip to the wire as it feeds through the gun. Proper tip sizing is critical to arc stability and weld quality. This tip is sized specifically for 0.045 inch wire and is intended as a direct replacement for worn or damaged tips during routine MIG gun maintenance. Installation is straightforward and the part is a standard consumable in production welding environments.

This contact tip is suited for MIG welding applications using 0.045 inch solid or flux-core wire across a range of material thicknesses. It fits into standard MIG gun assemblies where 0.045 inch tips are the specified consumable. Common applications include structural fabrication, light manufacturing, and maintenance welding in industrial and commercial settings. Welding professionals replace these tips regularly as part of scheduled gun maintenance to maintain consistent arc performance and reduce downtime.

Key Features

• Sized for 0.045 inch wire diameter for precise electrical contact and consistent wire feed
• Compact form factor at 1.5 inches length and 0.25 inches width for standard gun thread fitment
• Lightweight at 0.02 pounds, minimizing gun head weight
• Designed as a direct consumable replacement to minimize arc interruption during service

Compatibility

Designed as an OEM-style replacement contact tip for MIG welding guns that accept 0.045 inch wire diameter tips. Confirm gun thread style and tip seat geometry against your specific gun model before ordering.

Installation Notes

Contact tips are installed and serviced by welding professionals. Always power down and disconnect the welding machine before replacing a contact tip. Allow the gun and tip to cool completely before handling to avoid burns. Use the correct tip wrench or pliers to seat the tip firmly without overtightening, which can damage the tip seat threads.
