This is the second batch of these little PWM controllers I have bought from BG. I've used them in modifying small and cheap welding machines to give a more stable control of the welding wire feed speed. They work perfectly in this role and are very simple to fit. The lowest and highest speed is easily altered by soldering small resistors to the pot end connections so the range of usable speed can be spread over the range of the pot adjustment. I am very pleased with these units and at the price I don't think there is a better solution for my needs.

Great price for nice looking relays. Well spec'd and ideal for spares for my hobby mig welders which use these to switch power to te welding transformer. Arrived quickly and well protected with foam packing.

Converting a hobby welder to a Euro torch connector is a very worthwhile upgrade. It gives the opportunity to remove the torch easily or swap it for a different torch at any time. Fixed torches seem prone to damage where they emerge from the machine and tend to pull out and cause problems. Euro torches tend to be better built and withstand daily use better too. The procedure for fitting the Euro conversion is pretty straightforward and some machines such as the SIP topweld have provision for an easy swap to Euro. Others may need a bit more work but is well worth the efforet and lots of video's on the net to demonstrate what you need to do. At this price it's definitely worth the time to do the job.

Nice kit at a good price and making a simple job of converting a fixed torch to use with a Euro connector. Ideally the torch should be the type with two unconnected trigger wires or should be capable of being converted to two wires. Well worth doing the conversion as it makes the torch easily disconnected or used on different Euro connector machines.

Obviously very similar to the other multi modules by Jumper and IrangeX and hopefully will have similar performance. I haven't tried it in anger yet so will have to wait and see. Internally looks to be soundly made with good soldering on a neat board. Antenna lead is soldered directly rather than using a Ipex plug and socket which I feel happier with personally- no chance of cable disconnecting in use. A bootloader is installed so firmware can be updated easily via the mini USB port using the Github firmware repository and instructions. My only gripe would be that it will not fit a standard TGY9x module bay pin connector without the surrounding plastic support being cut away from the bay first. This is not unusual with modules but is a bit of a pain to have to do. Taranis should be fine. This uses a 'universal' module case and the excess holes are covered by the paper label to give a clean outer look. The label is a little large for it's recess so the edges seem to be peeling away a bit. Over time it will probably tend to unstick slowly. No great problem but could do with trimming and sticking again. The mdule case is a good fit in the bay and clips in securely. Overall looks good and should make any Taranis or 9x transmitter into a 'one for all' controller.

Nice 'industrial' looking unit with a sensible sized heatsink and good quality, well labeled connector block. Tested only with a 100w bulb so far but all works well and adjustment is smooth. If this stands the test of time I will be well pleased with my purchase.

Q: Only two connections on the unit. Is one for live in and the other for live out and if so, which is which? Is neutral not connected to this unit at all? Thank you

Amazing 11 day delivery from BG. Delivery times seem to be getting quicker and quicker- excellent. The little unit arrived with the pot socket on the board a bit bent but otherwise all was well. Must admit I was a bit confused by the fact that there were only two connection points and no labeling to say what went where. Other regulator boards seemed to all have three or four connections and these were labeled as IN, OUT and Common or Live in, Neutral in, Live out and Neutral out. In the end I figured the two connections had to be live in and out and since they weren't labeled it maybe didn't matter which was which. I hooked up a 100watt bulb using the left connector (nearest the heatsink upstand) for live in and the other for live out. Plugged in and stood back and switched on. No bang and turning the pot gave full range of brightness on the bulb-phew! Only slight niggle is that the first third of pot range does nothing with all the action coming after this 'dead' zone. I'll try on other loads and if necessary change the pot for a smaller value to get an even spread of power. All in all my first impression is very good and this module seems to be excellent value for money.

I know it's been said before but this thing is really tiny. Took a long while to arrive because of the virus but well worth waiting for. When it arrived I took off the cover to look inside at the build quality and make sure everything looked to be soundly connected. The whole thing seems well put together and wiring is neat and tidy. Board plugs have a dab of glue on them to ensure none come loose. Components are pretty packed together but nothing looks problematic to me. Got a ground and work lead and plugged them in. Did notice that the dinse sockets were not all that tight and moved when the plugs were twisted into them- not a big problem to sort. I used a 2.5mm general purpose stick and set the welder to 110amps. It ran a very nice bead with plenty of penetration. I've not done any more testing yet but first impression is good. Obviously the ultimate test will be how long the machine keeps working for. I am a hobby welder and seldom use bigger than 2.5mm rods so am hoping I will have a good service life from this little thing.

The second top ordered and arrived very quickly as well. Looks really nice except it's a little smaller than the other top even though also XXL and my wife is a size L. She's hoping to lose a little weight and is sure it will then fit perfectly :-)

Wife is size L and she ordered XXL which was just right for her. Looks really nice and she's pleased. Very fast delivery which seems to be becoming the norm now BG has gone over to Royal Mail delivery.

Seems like a good way to use a standard mig torch for euro fitted machines. Kit seems well made and trial fit proved all was ok. Cheaper than buying a complete new torch if the one you use is working well for you.

Fabulous little unit which works perfectly. If you dabble at all with electronic components then this is well worth getting. Very quick to use and fast readout. Should be simple to fit this in a case of some sort and make up a set of flying leads if wanted for in circuit testing. Really impressed and at the price it really is an excellent addition to the hobby workshop.

Have used these modular rectifiers for a welder before and they work very well. I would suggest going for a unit well above the expected power rating to give some headroom (this 150amp unit for a 100amp load). I think the important thing is to mount them on a good sized aluminium heat sink using some heat transfer paste and preferably have a fan blowing air over them. As long as the unit is kept cool it should give good service at a price well below the cost of a bridge made from four separate diodes. A neat and cost effective solution to high current rectifier.

The 9x seems to be a very reliable unit and spares seldom needed but it's great news that parts are still available from Banggood for this amazingly hackable transmitter. Those who know the 9x and it's foibles will be aware that one of the few weaknesses is the fact that plugging the battery in reversed WILL blow the mainboard. Usually this can be repaired but sometimes the board is damaged badly and difficult to fix so a spare board is a very handy thing to be able to source. Compare this with the later 9XR for which spares seem unavailable which makes them pretty dead machines.

Nice auto-darkening welding mask glass unit. Bought a cheap auto helmet a while back but the darkening system was very unreliable leading to frequent flashes of arc when using it. Bought this unit to replace the crappy one. Tested briefly and seems to work a treat. Runs off two AAA batteries easily replaced which I prefer to the coin cells soldred into my old one. These were supposed to be recharged by the solar panel which meant I had to leave the helmet by a window in the workshop which was a pain. I prefer to keep my helmet in a box when not being used. This unit has a sensitivity pot and a delay pot for the return to clear screen timing. Both work well and setup to your preferences is simple. The third pot on the flying lead adjusts the 'darkness' of the activated screen and includes the on/off switch. This can be mounted on the side of the helmet for adjusting in use. I haven't tried welding with it yet and only used a bright lamp and sunlight to test so not certain of the strength of the filter but assume it's a pretty standard maximum of 11 to 13 and lower strengths for gas welding, plasma cutting or grinding. Overall it seems to be well made and operates well.
