CONTACT TIP SIZE

Contact tips are available in standard sizes to match the wire specifications of the welding torch (.035, .045,

.052 and .062 inches). Some Tandem applications may require greater arc stability than others. If arc instability due to electrical transfer through the contact tip is encountered, an undersized contact tip may be required. For .035" dia. wire use a .030" contact tip and for .045" dia. use a .040" contact tip.

WIRE STRAIGHTENERS

Torch goosenecks' have a 22-degree bend for joint accessibility. The bend provides a wire cast condition- ing that forces the welding wire against the contact tip for positive electrical contact. If selected wire packag- ing counters the effect of the bent goosenecks a wire straightener (K1733-1) placed at the wire feeder may be required to re-establish a useable cast to the wire.
