165e pcb fuse

[greyshirtguy]

My welder is a 165 "TransMIG"...
Over time I have noted that it seems very similar to the Clarkes - so much so, I am sure they are rebadged twins.....

Anyway, for what it's worth, I can check my fuse value in the PCB...
and at least you could treat the value as a another piece of evidence when investigating your missing value.

Take a peek at some old pics of my welder internals to determine if you think they might be similar:



and the close up on the fuse holder....


Other note: The manual refers to an "Internal 1A fuse" when "Mains indicator light is lit but welding arc cannot be established"

What is the value of my PCB fuse??? Sorry, I never checked when I took these photos.... let me know if you would like me to open it and see..

I've got a couple of 165E circuit boards in stock (totally different to the above) & the back of the fuse holder is stamped up 3A...with a 4amp fuse in the holder! So, fit a 3amp or a 4amp & you will be OK. If it keeps blowing that fuse you have a problem somewhere.

err I guess I should have realised that there are many models (and versions from year-to-year)....and if that Clarke 165E is anything like this one then yes, it has very different internals (I envy those smoothing caps that mine doesn't have).....


That said, I am still 95% sure that one of those Clarkes is the same as my TransMIG165...(maybe it's the 165TE)

thanks guys i phoned the machine mart help line today and was told the fuse is 1 amp but i could only get my hands on a .75 so in it went.still no joy but the fuse didn't blow,the relay clicks but no power to the motor.weldquip could you please give me a price on a new pcb......thanks.

 

[madkayaker]

my guess was about right! Have you tried putting voltage onto the motor from a batter just to make sure it works? Have you got a multimeter (and know how to use it)?

 

[paul6693]

yes mate the motor is fine.

 

[madkayaker]

have you got voltage into the board? Does the trigger switch work?

 

[paul6693]

pass on voltage to the board (messing with eleccy makes you black and crispy when you don't know what you're doing) and the trigger works fine.

 

[madkayaker]

I remembed after i posted that the relay clicks so presume there is power.. Try takeing connections apart (one by one) cleaning any crud and remaking on low voltage DC doesn't take much to stop the flow

 

[paul6693]

cheers i will have a go at that tomorrow....off to bed .....dog tired..

 

[paul6693]

there is power to the board when crossed with a test lamp the lamp lights and trips the rcb to the downstairs wall sockets.... got a pm from weldquip cheers mate.

UPDATE took the board out only to find a trace was broken so i hit the web looking at pcb repairs.lots of info on this subject and opted for a conductive pen ,with these you simply draw the trace back in so a trip to maplins. the wise man in maplins told me there is too much current through these boards to use a pen and told me to solder a lenth of copper wire from twin and earth to join the damaged trace so this i did....success the motor turns great....happy days...ran off to get a roll of 0.8 and as soon as you put any kind of pressure on the wire the fuse blows....so what now....new board if so where from weldquip can't get one(i don't think)........please advise...cheers.

 

[madkayaker]

if they have the same board as 90 gas gasless you can have mine as i have burnt out transformer

 

[paul6693]

nice one mate do you have a picture of it to check...cheers.

 

[paul6693]

here's mine

 

[paul6693]

here's mine

 

[madkayaker]

its very different to the one in mine i'm afraid

 

[paul6693]

thought it might be it's an old set....many thanks for the offer.

I have an old 165e about 12 months ago the machine just stopped, every time you pulled the trigger the motor would run but as soon as you tried to start an arc bang the fuse would go.
My problem was the rectifier diodes one of them had the wire off.
Pic shows mig with new rectifier fitted (£50 from Clarke's).

 

[paul6693]

thanks for the info bigweld but this is blowing the fuse by just putting tension on the wire .
