Einhell Euromaster PES 160F - how to put together the kende switch HZ8B-20/3/4

Hello
I purchased an Einhell Euromaster PES 160F with a kende HZ8B-20/3/4 switch. It does not give voltage to the secondary winding in the range of 230 V. According to this diagram of a similar CEN 160 F / 1 welder, it turned out to me that there is a bad connection and I connected it according to this diagram.

It turns out that there is no secondary voltage in the 230 V range, because it does not supply the primary voltage from the switch. I dismantled the switch to see what the contacts look like, it turns out that they are in very good condition. However, I have my doubts about the arrangement of the cams, it seems that when switching 400V / 0 / 230V, only the upper contacts work and both at one and the other voltage all 4 cams are closed, they are inverted with the cutouts facing up. In both positions the contacts 1-2, 5-6, 9-10, 13-14 close. It seems to me that this is a problem not the operation of the welder. I am asking for advice on what the contact sequence should be.

Hello - according to the diagram, output from the transformer (230 VAC)
it goes to switch to pin 6. Pin 6 connects to pin 5, but pin 5 hangs in the air?

This diagram from the forum seems to me to be a similar welder than mine. I also do not know what about the free contacts 4, 5, 9. As I compared with my connections, it differs a bit in terms of connections, but my connections are somehow incorrect, because 230 V applied to the contacts, which the switch cams do not connect with others, and 400 V is connected so that both parts of the winding are connected in series. It seems that they should work separately for each voltage. Despite this, the voltage on the secondary is 47 V and can be welded, or maybe it should be like that.

Hello
I am assembling HZ8B-20/3/4, I have a problem with the last cam, I do not know what position it should be, when to close the contacts, will anyone help? I do not want to buy a new switch because it is two hundred.

I got a little tired of this specificity of the linking sequence. The diagram in the first post was not suitable for this welder and I had to arrange the joints and cams in the switch according to my logic. It worked, the welder works at 230 and 400, the lights indicate correctly and the fan works at both voltages. The cams have 4 seating options. Below the arrangement of the cams in the position of the switch on the voltage of 400 V. I switched one of the terminal connectors on the switch in the middle part, but I do not remember which one.

Scheme

Thanks for the answer, but I mean the switch itself, whether in positions 1, 2, 3, 4, 5, 6 there is a transition from 15 to 16 and 13 from 14 all the time to position. 0 has no transition. I have another flashing. it's just about the switch in the original. I undressed him because he was jamming and the last cam fell out, now he's scheming.

Ok, I figured it out and it works, but it does not give the wire on the item. 1 and 2, but it was impossible to weld in these positions, so I have success.
Thanks.

My switch, when the cams were all arranged in the same way, it is probably not original. Someone had to figure it out before, so the welder only worked on 400 V.

Hello
This switch broke again (kende hz8b 20/3/4) it's time to buy a new one.
I found two, different prices and the question is, does the cheaper one have the same cams in the middle?
You can see that the jumpers are different, but the center should be the same, probably?
I would move the jumpers on the outside from my old one.
Do I think right? Will it work? I have 0 knowledge about welders.
When removing the old one, I stuck the tape with the numbers on the switch on the wires, can you do that?

Ok, the point is, is this switch factory the same, it comes with the cams inside, and the jumpers are adapted to different welding machines or devices?
The question is, is the hz8b 20/3/4 switch standard inside? Do the cams in the middle differ, the jumpers I understand are different.
There is the same switch for Einhella 150 190, but does it differ in the setting of these jumpers?

You must have a switch wiring diagram.
The symbol hz8b-20/3/4 itself does not necessarily define a specific switch with a specific connection system. Switches 230/400 can have a system, for example, with 3 contacts in the 230V position and 3 contacts in the 400V position, or 4 contacts in the 230V position and 3 contacts in the 400V position.

There are also those which, apart from the above, have 1 or 2 closed contacts at 230V and 400V, and open in the "0" position.

Einhel BT-GW 150 does not have a 230/400 switch, because it is only for 230V.

Thanks, to be sure, I bought this one for 150.

I repeat that the Einhel BT-GW 150 does not have a 230/400 switch because it is only on 230V.

It is worth repeating after NIX that "The symbol hz8b-20/3/4 itself does not necessarily define a specific switch". Today I am rummaging around the welder about which it was in the first post. It seems that HZ8b-20/3/4 is available in at least three versions and probably the easiest way to distinguish them is the number of switches. Welders only on 230V, one switching 0/230. 230/400 welding machines, three switching 230/0/400 and the so-called automatic flaps with a switch in 6 positions. I have read a few threads and checked in several stores and it seems that not everyone gets it, and in one of the stores they offer in exchange for a withdrawn three-position switch - a Polish six-position product. Even in this thread there are pictures and descriptions of the various switches. Someone who came up with one symbol for many products had an imagination. The sad thing is that this is not an isolated case.

What do you think about the connection below.
400v short contacts: 1-2.5-6.9-10.13-14
230v short contacts: 3-4,7-8,11-12,15-16
Bridges: 1-3,7-11,10-14,14-16

This is probably the diagram of the Einhell welding machine. If the transformer has such windings (the simplest 230-400V system, only 3 outputs), it can be connected in this way.

Trafo has 4 leads, but the middle ones are connected together, I'm just wondering if I don't have reversed windings now because I have 0.4 Ohm at 230v and 0.6 Ohm at 400v

If you measure correctly (because fractions of an ohm is an ordinary multimeter in the 200-300ohm range, it "on average" accurately measures ...) then 0.6 ohm should actually correspond to 400V, if 0.4ohm is 230V.

I measure in the range up to 200 Ohm, I corrected that diagram and retraced all the inputs and outputs to the switch, connected it and everything works.

No to super !

pzdr !
