Argon Co2 mix

[bloke]

These are my first welds with Argon CO2 mix using Clarke 151en.
Slight breeze outside the shed. Had used gasless but no where near these for comparison.

any comments.............?

They look 'cold', your power setting is probably too low.

cold welds

should i get the 'blue ring' around the runs? there is very slight blackening on the underside and a few areas of penetration on 2mm mild steel plate.

 

[Wozzaaah]

The blueing is caused by the heat so it's normal.
What wire diameter and power setting did you use? The 151 should penetrate 2mm sheet easily.

power setting

setting was 1 2 min wire speed 5 when I tried it on A2 min wire speed 5 on another piece it blew holes in it.

2/3 switch is disabled if 1 is selected, it's only enabled when the first switch is set to A so you've done those on it's lowest setting which is why they're cold.
The next highest setting is 1 max then I believe it goes A - 2 min, A - 2 max, A - 3 min, A- 3 max, so you have 6 power settings in total.
Try again on 1 max and see what difference it makes.

Cheers for that advice,

Will do, I read the Clarke guide that came with the machine, but I think it may be off on the settings.

Bloke, take a look at this post, which gives more details about the correct settings for the 151EN.

Clarke got the settings in the manual wrong - some geezer at a desk, I guess - so if you follow the settings Malcolm posted here you should be okay. I also went by the Clarke manual when I first got my 151EN, with some odd results.

Hi Keith19

I have bookmarked the link you posted, that looks a bit more like it. Next time I get chance I'll put in some practice.

Cheers
