Hi all
I have a Cebora boxer 175 amp mig and have been happy with it for odd jobs over the years using co2 and 0.6mm wire on thickish metal.
Today I have been butt welding a 1mtr x50mm strip into the rear skirt/chassis section of a transit van. After I re-read this site's excellent guides again last night in preparation as I am not used to thin metal.
I started this morning outside but with shields around to prevent the wind blowing the gas away (reasonably effective I thought) I set the welder to power I of 7 and using .6mm wire started burning holes
(not unexpectedly) I played about with the wire speed and found 5 1/2 about the best, I tried the on off method which worked a bit better and then ran out of co2
I then found my spare pub bottle was also empty 
.
So I had to try my last card and used a very large bottle of Argoshield heavy that I had been given a couple of years ago, although it worked it took ages but after I had ground off the excess weld and touched in the many holes it did not look to bad and is hidden behind the bumper.
The biggest problem apart from me
is I think my welder only goes down to 55amps minimum.
These or taken from the data table on the welder
28A 15.4V - 120A 2V
X........20%.....60%.....100%
I 2......120A....70A.......55A
U2......20V.....17.5V.....16.7V
X being duty cycle
I 2 being welding current
U2 being secondary voltage
I am right can this really be the minimum setting ?
Is Argoshield heavy any good for thin metal ?
any tips gratefully received.
