| THYRISTORISED
MIG/MAG (CO2) WELDING MACHINE
IMAGE
PROCESS: Continously feed wire
in the form of spool is used as electrode and the arc is shielded
under the cloud of insert gases such as Argon, Helium (MAG)
or mixture of active gases or most commonly used gases Co2.
- Fully thryristorised closed loop feedback
control enables remote control of Welding current and voltage
for thyristorised models
- Arc conditioned feedback system ensures
constant arc length, eliminating need for highly skilled
welder.
- Instantaneous Arc Starting.
- All position welding possible. High metal
deposition rate. High welding speed. Low Hydrogen conten
wires possible.
- Very wide range of metals, such as mild
steel, stainless steel, carbon steel, aluminium and their
alloys with proper consumables and gases can be welded.
- Preflow of shielding gas interlock. 4T
function with crater control which eleminates defects like
cracks, gas entrapments.
- Globule Formation at the top end of wire
eliminated.
- Built in solid state devices protects the
machine against single phasinh and thermal overloading.
Lamp indication for fault is provided on front panel.
- Facility for power source to trip in the
event of short of output terminals accidently for a period
beyond the preset time, can be provided.
