800 AMP TANDEM MIG TORCH
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.
