MIG/MAG, how does it work ?
Stren gth s
In the torch cable:
- Gas
- Wire in the sheath
- Electric wire
(+ Water cooling when selected)
•
•
•
•
In the torch:
- Nozzle
- Contact tip
- Wire
The welding:
- Shielding gas
- Arc
- Weld Pool
- Welded metal
Quick process
High quality work
For intensive use
Easy to use
O p ti o n s
• Work with an internal or external wire feed unit
• Work with water cooling
• Work without ext. gas using gasless cored wire
(Flux cored)
NO GAS
Cored wire
Flow
Note: welding outdoor is not possible using external gas
Metallic wrap
The shielding gas is contained in the cored wire, and released during welding
1- Reverse polarity
2- Change the contact tube
3- Change the liner
4- Change the drive rolls
(except Universal 2P)
MIG/MAG, choose the right equipment
• Depending on what and how you wish to weld,
different packages will be required.
the MIG/MAG Torch activates
the welding process and transports
wire to the work piece.
Choose your model:
the Wire Feeder brings the
metal wire to the torch.
- the material
eg: torch for Alu
- the welding current eg: for 250A max
- the contact tips eg: for Alu Ø0.8mm
- with/ without water cooling
- other accessories (nozzles, liners...)
Choose your model:
- with / without water cooling
- the Drive Rollers
eg: for steel Ø 0.8/1.0mm
the interconnecting cable links the Power
Source to the external wire feeder.
the Power Supply provides
the welding current (A).
Choose your model:
- with / without cooling system
- the size of cable eg : 5m interconnecting cable
- Single phase or three phase
- including external wire
feeder or not
- with / without cooling system
GAS
Choose your model:
generator + wire feeder
Remark : we distinguish three main types of power supply :
- "Power source" only deliver welding current, and need an external wire feeder
- "Compact models" have integrated wire feeder
- "Hybrid models" have integrated wire feeder, but allow the connection of an external wire feeder
compact model
the Earth Clamp is attached to the
piece of metal and closes the electric
circuit, needed to let the current flow.
Choose your model:
- the welding current eg: for 350 A max
