Inverters are pretty universal and use either 5K or 10K. As they are simple voltage inputs, the value is not critical.
No hooking a 150 ohm Dialarc pedal to an inverter is not a good idea I seem to remember that is what caused the problems in the other thread.
Transformer-based welders tend to use very little electronics. Most older ones were very low-tech and required high-power rheostats for the current control. Each footpedal or remote control was specific to a particular model.
If you can get a schematic of the footpedal it uses, it often has the values on it.
Thanks for the mail.
After all the trouble with the welder and the firm who (did the job) so to speak
I have only used the welder 3 times and thinking of selling it as i find it hard to stand for more than 15mins.
Yes butters did do there very best for me and i did thank them on the site and by private email.
And better still i still have the miller foot pedal sitting in a box doing nothing,might go on flee bay.
I have tried to do some ali welding but eveytime i go near ali it looks like chewed toffie.
My mig welding is good my tig welding on s/s is good ish welded a rear exhaust can for a mate for his ccm he was very happy with it, but its the ali thats doing my head in, it might have beaten me.
I will give it a couple more goes and if its still the same i will sell the welder and all what came with it,regs,rods,foot pedal,ect,ect its like new never seen out side lives in the garage,and if i sold it i could send my bottle back to Air products that will save me £70 a year.
I would have liked to have done a ali weld just to say i can do it and i have a friends plane that his dad made some 20 yrs ago in ali and the stand is broken
But if i went near it with my welder it might just go to mush and he would not be happy as it one of the last things he gave him before he died so i dont want to mess that up.
I wanted the welder for my model helicopters as they are mostley ali and i would have liked to had a go at welding some parts.
Its true what they say you never stop learning.
I will let you know how i get on, you might even see it in the forsale post soon. boxed as new used 3 times mint just dont know a price yet.
If so, with the best will in the world, ali welds will not look great.
I use DC ali on my little Rehmann and -- on thickish stuff -- say over 4mm -- the welds are functional (although I'd never use them on structural stuff, to date I'm just putting together a plenum chamber for my little Turbo car), but chewed toffee pretty much sums it up!
Yes i had used the welder on ac for ali and it still looks like chewed toffee?
Even using new ali as soon as i get near it to start a weld the metal gives up
a bit like using a blow torch over a block of butter.
I have played with all the settings tried low power high power middle power and its still the same.
I have welded cars for mot work for over 20yrs so i know i can weld,but me and Ali dont get on.
I will have a go next week and see what i can do.
Were about in lpool are you? and what plenum chamber are you building.
Ali is funny stuff to weld, it's sometimes difficult to see when the pool forms then once you've realised that it has it's too late and the metal 'slumps' away. How far away from the workpiece are you keeping the tip of the tungsten? The arc being cone-shaped, the tungsten needs to be pretty close or the heat is spread out too wide.
Why not describe what you're actually doing, metal thickness, tungsten size/type, gas flow etc in a new thread and someone might be able to point you in the right direction?
