welding settings

[ACE HIGH]

I built a steel 32 ft yacht 36 years ago with a 150 amp arc welder,it overheated badly so I set up a 12 V car battery alongside it with a heater fan,it was a standard Smiths type probably from a Rover 90,it worked a treat.
Or simply buy a 240 v electric fan and with a bit of playing around with cardboard or ply make up an intake for it,even drill a hole or holes in the side.
The old smiths heater fans put out a huge volume of air,I assume modern fans are just as good,flog the one out of your donor!
Maybe a bit of roof drainage pipe throught a hole in the side will do it.David

Thats a good plan ACE, i tried similar myself but it didn't work for me.

Deciding now whether to go for a new Portamig or a Lorch Pro Synergic.

Ooo, I have a Portamig 185 from and its great... doesn't like a 13amp plug though, a 16amp commando is the required item, simple to wire into a spur.

Maybe a vacuum cleaner,either blowing or sucking,perhaps remove bag and final filter, will cool your welder.Only a small hole will be needed or use the fan head.
I painted an Austin Kimberley with a vacuum cleaner 30 years ago using oil based house paint and a very good job it did too! Cheap and quite pro.
I also stuffed my wifes vacuum cleaner 30 years ago when I accidentally "sucked instead of blowed" the red hot charcoal ashes from a producer gas unit I made for an old Massey Harris Tractor.Yes it worked well.David

Now then, that's talent!

Hi Steve,

Your 60x40x3mm box section is coming in tomorrow, 6m length for £20.

If you come down in your everyday car you could take the mig gas bottle with you.

Perhaps an electric garden vacuum/blower,a huge volume of air?????David
