Low cost and profitability are key
business objectives, whether the
product offering is a wheel, a
water tank, or a truck frame. It
used to be thought that on the
road to lower cost, quality had to
be sacrificed. That’s no longer
true with Tandem MIG welding.
The following factors affect
pricing per welded part:
•
Capital Equipment
•
Overhead
•
Labor cost
•
Part production rates
Lincoln Tandem MIG welding
systems are designed to produce
quality welds at welding speeds
well above accepted single
wire processes. The unique
engineered output control of the
Tandem MIG dual wire process
is designed to overcome the
barriers limiting the travel speed
capabilities of conventional single
wire GMAW processes.
INCREASED TRAVEL SPEEDS
• The combined contribution of two separate welding arcs in one weld pool
provides the control to overcome the lack of follow tendencies of single
arc processes.
INCREASED DEPOSITION
• Two small diameter Tandem MIG wire electrodes provide higher melt-off
rates per current drawn when compared to a single larger diameter wire
electrode at similar current draws.
IMPROVED THROUGHPUT
• Higher travel speeds and higher deposition rates reduce part welding
time cycles.

Increased deposition
on thicker materials
reduces welding time
and distortion.
Fast travel speeds on thin
lap welds increase the
number of parts per day.
"Loading the manual" means you need to wait until the file loads and becomes available for online reading. Some manuals are very large, and the time they take to appear depends on your internet speed.
