You can do an overlapping weld but do both sides or joggle the floor and weld both sides

Just had a quick go with the welder,go easy on me its my first time using one

At first they were all pigeon poo but then I managed to get a good flow going but none of them penetrated.

I cut a slit with a 1mm girding disc but couldn't get it to go over the gap.

Then I had a go at joining two pieces together which could have gone better lol.The last pic at least shows that I got somewhat of a proper weld as the metal broke and not the weld.

The best results I got were with the gas on 4,power on 1 minimum and wires speed 5.

Ill have another go tomorrow after I read your replies :)

Had another go today and got a much better looking weld with penetration but as soon as I try and join two pieces together I just blow a hole in the side a start from and can't get he weld to cover the gap.

What am I doing wrong?

Looking at your welds they are getting there but i would recommend the following settings

 

Try doing tack welds on the slits approx one inch apart then pulse weld in between, these are just a series of slightly stronger tack welds that overlap each other.

 

The wing metal is a tad too thin to seam weld so get some thicker metal of at least 1.2mm thickness and then try that for seam welding.

You are prob holding the trigger down too long.

 

As Neil says you need to pulse weld. Hold the trigger down and do one or two circles and stop then repeat.

The sills from m machine are 1mm,is that mush different to weld?

No they are fine to weld. I have them fitted to Paddy.
