contact tips are easy-to-use and
high performing - they provide better arc starts,
less spatter and more consistent welds - and also
last up to three times longer than competitive
brands.
Sleeved and aluminum armored necks 
available in multiple length options for optimal 
weld accessibility and improved operator
comfort.
Trigger is sealed from outside contaminants, 
simply replaced and absorbs less heat than a 
metal trigger for long-life, greater arc-on time 
and lower heat output.
Trigger guard instead of full size heat shield
allows access to tight spaces while protecting
trigger from damage.
Ultra heavy-duty steel monocoil power cables
are highly resistant to kinking for exceptional wire
feed in abusive environments.
Back end with durable rigid strain relief and 
easily interchangeable direct plugs and trigger 
leads connect to wire feeders and machines 
from major manufacturers and allow simple
maintenance.
Power pin liner changes quickly without set 
screw for user-friendly maintenance and reduced 
downtime.
