Tips:

Contact tip to work distance (CTWD) is the distance from the end of the contact tip to the work piece (i.e. the steel plate). Sometimes welding documents will reference the electrical stickout (ESO), which is the distance from the end of the contact tip to the top of the arc.|
The normal recommended CTWDs for flux-cored wires are long [1 in. (25 mm) average] compared to short circuit MIG welding [3/8 in. (10 mm) average]. The wire becomes electrically hot as soon as it touches the inside of the contact tip. This longer CTWD for cored wires results in a split second more time of resistance heating in the wire, which allows the core elements to fully react or activate and provide proper protection of the arc. Note: If the CTWD is too short, incomplete activation of the core elements may occur, potentially resulting in gas marks or porosity on and in the weld. However, too long of CTWD (with no change to wire feed speed) can cause an unstable arc, increased spatter, and decreased penetration.
