The short-circuiting metal transfer
The short-circuiting metal transfer mode is the low heat input
mode of metal transfer for GMAW and has higher electrode
efficiencies, 93% or more. The low heat input reduces
weldment distortion and makes it ideal for sheet metal
thickness materials.
Root pass welding process
The MIG-350i gives precise, clean welding
performance, and also support optional root
pass welding process. Our new control
technology ensures excellent arc ignition and
welding performance, obviously reduce the
time for cleaning the weld spatter.Four-Roll Drive System
4-Rolls wire-feeder with strong feeding motor.
Four-roll drive systems deliver the electrode to
the welding torch.It provides a stable wire speed and
is popular for industrial applications.Arcforce correction (welding characteristics)
During the welding process, arcforce prevents the electrode sticking in the weld pool with increases in current.
This makes it easier to weld large-drop melting electrode types at low current strengths with a short arc in particular.
