Hi Guys,
I don't think I've mentioned this before, appologies if I have, but as there's been messages in various sections recently about using higher powered welders and blowing holes in thin plate, specifically in car body-work...
when I did the course about 18 years ago it was mentioned that it's very difficult to use an arc set on thin plate.
Then one of the guys who'd been welding for years and was just there to get coded (more money, apparently) said he's demonstarate how easy it was.
Basically he got the thinnest metal he could find, and set up an arc set using very high current.
To show us what happens he cut a groove through the plate and then he showed his method of doing the job...
use the torch as normal with a rod in it but have a second rod in your 'other' hand, as a filler rod, rather like gas welding.
The result was a wider than normal bead but no blow-through!
I reckon with a bit of practice and using the right material anyone should be able to weld any thin-ness(!) of metal with any kind of welder.
The instructor said he'd been welding for 30-odd years and he'd never seen that method before.
What do you think of it?
Regards
Peter
