I would still try powering up the motor as they can die leaving a short circuit that blows the board so fitting a new board will not help - but it sounds like a board issue - worth removing & visually checking -( some have tiny hard to spot glass fuses as well as a main fuse ) they are not super...

I have a transformer based Mig with 7step voltage that I bought new when 18 years old - now I'm well into my 50's and it still works the same as it always has - also got a transformer air cooled ac stick welder bought new aged 12 still working - I don't see anything wrong with them ( also got some 2...

Try to get to the 2 wires taking power to the wire drive motor & confirm if you have voltage when the trigger is pulled -if there is it's a bad motor which has brushes so could be as simple as new brushes - you can test the motor by connecting a 12volt car battery to it - they are typically a 24...

That thickness is hard to weld even if experienced with the gear your using so no disrespect on your first try - I have helped several people who have similar if not the same welder bought from a supermarket / big box store & they mostly had the same problem - the wire speed will not go low enou...

In principal yes I agree - ( unless working for Nasa maybe ! ) but if your at a stage where you are routinely removing giant blobs of filler metal especially aluminum from your tungsten try to keep one wheel for removing contamination & another for finishing as you can quickly load wheels up to ...

Most standard saws tend to have rather high RPM for metal unless you can find the real old model ( can't recall number ) with the worm drive but I not seen one about in a long time - think they long since vanished due to the double insulation safety Nazis ! the diamond blades do have a niche use - t...

Not only are the flash back arrestors directional - the hoses are in so far as they have " hose check " valves fitted ( in the UK @ least )to the torch end - if you try the pipes the other way round ( threads are the same both ends ) no gas will flow - visually never seen direction arrows ...

You could give Comic-Con a try with that on !

Welcome to the forum Johnny449. Plenty of folks should chime in on this as many members weld a lot of aluminum once they catch up ( I rarely do so limited experience ! ) I would say if you have limited or no experience your on the right track & have some beads that look OK - in answer to your qu...

As no one else has spotted you yet ! welcome to the forum RDP57. Sorry I got no real input on this as I really only braze " old school " with oxy but hopefully there will be someone here that can help - it just takes a while with members available time & being all over the place geogra...

Needle guns are'nt that bad - I don't hear too well either but it has something to do with my younger days when I was the go to guy for removing wartime concrete structures & tree stumps etc for farmers ! nice one on the exempt jury service though .

Did you try turning it off then back on ? !!!! site was unavailable here in UK for about 3days - I initially assumed it was a glitch with the VPN location as it does sometimes do it - I even tried it with my real IP address which kinda goes against the grain but it made no odds - very glad site is b...

A needle gun works well for peening & as an added bonus everyone knows your working !

Given the inability to get the crap off the inside or purge it looks a good job - I've had a few of these on boats & they are often kinda eaten / corroded / suffering a form of electrolytic damage & just won't weld - I often braze them of choice believing that it is slightly more forgiving i...

Glad it worked out for you - sometimes less than perfect is good enough using only what you have by & the next time round will seem easier - besides by then you'll have had time to make an excuse to buy a plasma cutter !

All solid advice - I often have used hole saws up to 4" on site where I had nothing else - my 2 cents is I do the solid mandrel thing & it works well - if you are free hand drilling rather than pillar drill I would clamp the piece down on something solid like 2" so the mandrel has a go...

@ Alan. Thanks for the clarification - the process I and others are replicating is virtually instant so not quite the same thing - for anyone interested the one I saw a video of is marketed by " Tig Brush " - I agree that a 12volt supply is ample for long term electrolysis by submersion of...

Glad it's all coming together for you - volts sound about right - they are rarely that precise on those machines - even when new I think they all got stamped with a number from a singular test model - not specific to that unit on test at build - when you say timing set past TDC you do mean before TD...

Your saying borax mixed as a paste / solution will passivate stainless ? never heard of it or tried it. As to 12 volts DC I don't think from my experience it's very effective or fast unless your using a very strong acid solution which kinda defeats the point of using electrolysis- normally initial c...

Assuming it's a conventional generator & the AC is being produced by a 2 pole alternator I think it's safe to assume the governor RPM's is off by the difference in frequency of 42 > 60 so proportionately the volts will be down a similar amount as this unit looks too old to run an AVR - so a chea...

No worries ! I've never seen a real one except in a video so I can only tell you what I improvised which seems to work OK - for the life of me I don't see where they get the price for a commercial one. I rather think you can use a small amount of any acid available to make the solution conductive as...

Sorry Mick - I don't have any pictures or any way to take them - I never went digital - only 35mm film ! I've used several power sources - I had always believed the commercial ones use around 25 > 30 volts & around 20 > 30 amps but could be mistaken - AC has a more aggressive cleaning action but...

That's interesting - I never tried anything but phosphoric as I believe the expensive machines use that plus I keep it in stock for rust stain removal on boats & it's fairly cheap & is often used to clean stainless in kitchens / toilets etc - I never experimented with anything else. I have u...

My point is you don't need to drop like 2grand on a purpose made machine - they are so easy to improvise.

Maybe they could snap up Wyatt ?
