3. What is it ?
3
High performance MIG/MAG welding using two electrode.
The process utilizes two welding power sources and two wire feeders acting in tandem.
Doubling the welding output.
Electrically isolated from one another and are controlled independently.
Independent control of the two welding arcs.
4. How does it works?
4
Two independent welding system synchronized with
one another.
The separate wire electrodes are fed into a single
torch via separate wire feeders.
Both wire electrode can be synchronized
accordingly using twin controller.
5. Step 1
Lead electrode- rapid current
increases and begins the process of
creation of molten droplet
Trail electrode-current reduces and
relaxes plasma force as the droplet
separates and approaches the puddle.
Step 2
Lead electrode-peak current creates
a molten droplet sufficient pinch force
to begin separation
Trail electrode-arc reaches a
minimum current level and maintain
the arc without additional metal melt-
off
Step 3
Lead electrode-reduction in current
relaxes the plasma force as the droplet
separates and approaches the puddle.
Trail electrode-rapid current increase
begins the process of single molten
droplet
Step 4
Lead electrode-arc reaches a minimum
current and maintain the arc without
additional metal melt-off
Trail electrode-peak current creates a
molten droplet sufficient pinch force to
begin separation
7. Advantages
7
Two separate electrode can be controlled
independently.
High welding speed.
High deposition rate.
High degree of flexibility.
Can be used on thin and thick sheets.
Different wire feed speeds possible between the lead
and trail wire electrode.
Synchronizing of both arcs promotes process stability.
8. Disadvantages
8
• Increased formation of welding spatter
• Adhesion of spatter to welding tip
Application
• Automotive industry
• Shipbuilding
• Railway vehical
• Aircraft industry

Life is made of ever so many parting
welded together.
