Inverter Migrate: How to Set Welding Voltage & Wire Feed on WELDMAN MIDI MIG 220 MMA for MIG/MAG

Hello all

He purchased an inverter migrator for small home work MIG / MAG WELDMAN MIDI MIG 220 MMA



There are two knobs for setting the MIG welder, one is the wire feed, which also regulates the welding current (at least I think) and the second knob setting the welding voltage. What is the relationship between these knobs, how to set the welding voltage ?? At the moment I am setting the voltage by trial and error.



I am asking you for a brief instruction on how to set up such a welder.

Voltage (and indirectly current) depending on the thickness of the material being welded. Advance so that your pipe does not repel, because if you give it too big you will feel clearly that it repels you. If it's too small, the wire in the husk will burn you. Wire the wire no further than for 8mm (between 5 and 8mm), gas 8-10l / min (but it also depends on the diameter of the husk, with larger diameters more gas).

In this welding machine you have two knobs from MIG / MAG and one from MMA. Extreme on the right is the MMA knob and you set the welding current there. The middle knob is the MIG / MAG welding voltage and the extreme left is the feed rate. The rest, as the colleague wrote above, the wire would not repel and not burn him, and the tension depends on the thickness of the material. V / mm tables are available, which will help you to start adjusting the tension to the material thickness.

And could you direct me where to look for such tables.

Thanks for your help, I'll try and see what will happen to me.
greetings

Hello . Buddy, do not bother with the tables. The tables are for theoreticians who have practical knowledge about welding like wolves about stars. Collect different bald thicknesses from 0.6mm to 6mm. Then start with the thickest ones. Set the MIG / MAG welding voltage to half of the range and the wire to the middle of the range. Pave two pieces of sheet metal. If the wire will repel the handle, increase the voltage but if the edges of the weld are flooded, reduce the wire. I will tell you only that practice and once again practice. After some time you will know how to set the material thickness for yourself and nothing will happen to the tables.

Hello! My weldman midi mig 220A broke down probably.
Mig - he stopped supplying wire and welding. (the motor works because it moves the wire in the load mode to the wire)
Regarding the voltage shows 8.3V, as I push the button jumps for a moment to about 60v differently and drops to 8.3 all the time holding the button.
As the voltage jumps and I want to weld it, it probably secures itself and falls on 0V (I leave 8.3V from the material again)
First, she started to stop and then I did not even hear the connection of the relay I suspect (he could stick together).
In MMA mode, it works quite well.
It's on warranty so I do not move.
Bought on alllleedrogo. I am now looking for a website and .... this is the problem here because I can not find a weldman service.
As if someone somewhere somewhere I will be grateful for your help.
Greetings!

If it is covered by a warranty, ask for a salesperson's service point or let him take care of shipping to the site.
