    Hello. I am buying an inverter welder and I can not really decide on a particular model. I found three DEDRA models. There are considerable price discrepancies and I am a bit surprised because three models have a similar range of amps.
    - DEDRA DESi199BT
    - DEDRA DESI210BT
    - DEDRA DESI201.
    Does anyone have the above model and is it checked? I would like to weld steel profiles up to 3mm and weld the hinges to the gate and I would not like to be surprised that the welding machine can not do it. As far as I know, the first two models are made in a different technology than the third one - probably in a newer one. But why is the third model the most expensive if it is made in the older technology (unless I'm wrong)? I would be grateful for your understanding and cordial help. Greetings.

    I had the opportunity to repair the DESI201 model recently (a burned out switch) and by the way I slept a little with this clutch and it was fun. A friend who gave it to me for repair has it for quite a long time and nothing wrong with it after that we had to replace the sockets for welding cables because they burned out (poor quality of sockets) the other friend also has this model and does not complain.

    Thank you very much. I will definitely take your advice into account when buying.

    Do you also take into account welding machines of another brand? Tomorrow at the workshop I should have a new MAGNUM SNAKE 205D VRD welder and if you like it, I will describe your impression as to the quality of workmanship and how it is welded in comparison to DEDRY DESI201 which I had the opportunity to use. MAGNUM is on IGBT transistors as well as your first two types and DEDRA DESI201 is on mosfets.

    I've heard that IGBTs are inferior to repair. Besides, they are cheaper than mosfets, so something must be there. However, I am waiting for the impressions from the use of the welding machine.

    Is IGBT worse to repair, I do not know, mosfets are cheaper but for them there are more of them, so it is difficult to determine. And now as for the MAGNUM welder's experience it seems to be better quality than DEDRY, welding and net cables are definitely thicker and better quality at MAGNUM, the slots here and there are probably the same. You just have to screw in the wires well and check that they have not loosened. Is there any difference in welding it is difficult to tell because I do not have a direct comparison. I weld only amateurly and in my opinion welds, as well as DEDRA and MAGNUM, come out in good quality.

    Ok, so I decided to use the DESI201 inverter welder. The welding machine so far is a great thing, there is nothing to compare with the transformer but there is one but. During welding, the electricity meter starts to loudly and it scares me a little. The meter has an old type, i.e. inductive and I wonder if this welding machine produces such disturbances in the meter work? I would not want to damage it and have an even bigger problem. Earlier on the transformer welding machine I did not have such a problem. Can anyone help me with this topic? Greetings.

    And what type of fuses do you have? If you have an automatic one, check if they do not seem to hear these sounds.

    B16 type S overcurrent fuses. But it is rather a meter. Has a friend met such a phenomenon?

    I met with such a phenomenon, but just in the case of ordinary automatic fuses (those screwed in) with loud buzzing during welding because they were on the edge of the action threshold. I suspect that in the S type fuses this phenomenon may also occur because the welding machine requires 25A protection.

    Hello. And why did not you take DEDRA DESi199BT - it has 100% 125A and 4 year warranty for the consumer. I'm just looking through the net, but I think I'll buy just 199 because of the warranty - 4 years for Chinese is spooory plus.

    The snake exchanged by me has 100% at 163A. In my opinion, snake welders are of better quality and above all have a solid switch, which will not burn quickly.
