D/F Machine Specialties MIG Wrench

The contact tip is a very important part of the torch and the welding process. D/F contact tips do last a long time, but like any consumalble they need to be changed to maintain quality welds. It is important that the D/F Contact Tip Wrench is the only tool used to loosen or tighten a D/F collet nut or threaded contact tip. Threaded tips and collet nuts (for slip-in tips) should be threaded completely into the front end, tight enough so they do not move, but only hand-snug as to not damage the threads. When tightening, pressure should be 30 lbs., or as snug as hand-tightened. Never use another wrench or tool to apply more torque to this wrench
