An Inverter MIG welder is an electronic piece of equipment that converts AC Input to a stable DC Output.  A wire feed motor with a continuous welding wire is connected to this output via a welding torch,  to enable consistent blowing of the wire when shorted to the workpiece.

WHAT'S INCLUDED:

• 24AK torch
• Wire feeder inside the machine
• Digital display
• Mask and brush and 0.6/0.8 rollers
  
• Black cover and black panel
• Brown box

HOW DO THEY WORK?

Inverters use a system of hi-speed switches to facilitate voltage regulation. The inverter works by increasing the frequency of the power supply from 50-60Hz AC (High Volts Low Amps) to 10000 -  20000 Hz AC (Low Volts High Amps). It then pushes this Low Volts High Amps through a small transformer and finally through another rectifier to convert back to welding DC. The high frequency switching in the inverter module can be done by either MOSFETS  (metal-oxide semiconductor field effect transistors) or preferably IGBTs (insulated-gate bipolar transistor).

ADVANTAGES ON MIG INVERTER WELDERS:

• Use less electricity
• They are much lighter than traditional models
• Precise settings options
• More controllable
• Multiprocess

COMMON USES:

• Sheet metal welding.
• Home improvement, automobile, and automotive industry.
• Fabrication work of pressure vessels and steel structures.
• Heavy constructions such as building materials and bridges.
• Welding of pipelines.
• Repair of automotive.
