MIG wire feed motors/assemblies

https://www.aliexpress.com/item/32826045278.html I fitted this to a clarke 150, had to wire in a brake circuit with the help of this forum to stop it running on and wasting wire everytime I stopped, made it useless for bodywork continuous tacking style welding too. I think I would have been better off with the type with the spur gears rather than the worm and wheel that I got.

Although the motor I got says 24v and 4A in reallity it is about 1A max at 28v while fully loaded manually and about 0.5A when feeding wire. I'm sure most wire feeds are chinese rated too and the power rating is the maximum power output or input not the actual power in use which will be somewhat reative to the load.

Changing from a 10W motor to a 25W unit will double the current requirement. The wiring will handle an extra Amp or two without issue. The power semiconductors on the PCB that drive the motor are probably going to be OK too - most driver components will be rated at 5 Amps or more. To confirm that, check the part numbers of the large semiconductors.

Thanks for that.

(you don't do repairs/upgrades for a living do you? You seem to know a fair bit about this...!)

I have a feeling it was Rosepuds or similar, but he hasn’t been on the forum for many years that I’m aware of. He certainly hasn’t posted, anyway.

No worries. Thanks. I have found his email address on a couple of old posts where others have recommended talking to him. Might drop him a line.

Just a heads up, you'll usually end up recieving a "40w" version of that metal framed feed motor from china, i've ordered a few and aside from one 25w one i crammed into a little cemont welder on another thread i've always ended up with the 40w version regardless of which i actually ordered.

It'll probably still be fine wiring wise and the frames are identical but the motors are larger on the 40w ones obviously and they come with rollers groved for 0.8mm and 1mm wire rather than 0.6 + 0.8 so you might have to order another roller if you wanna run 0.6mm wire, just something to bare in mind

Good to know. Thanks!

Same tat as ebay though. Sorting the wheat from the chaff is impossible.

Yabutt ...."Cheaper" than ebay.....

Thanks for that.

I used to be a computer hardware Field Engineer, but playing with MIG welders - and EVs - is just a hobby.

Thanks. I had seen those and emailed Techarc but havent got a response. I dont mind phoning but figured that an email with details of the welder etc might be more helpful.
