MK Products 3/8" Spring Loaded Contact Tips
The use of the Spring Loaded Tips has shown to improve wire to tip contact significantly, especially while welding aluminum in DC Pulse Mode.
Incorporating a wrap-around spring material, a ceramic "puck" pushes up against the wire forcing the wire to make 100% positive contact with the internal face of the contact tip.
The constant touching of the wire to the tip eliminates "electrical gaps" in the welding voltage sensing loop, which many welding power sources utilize for sensing arc voltage values.
- Tips are 3/8" overall diameter
