So had a shot at a Turbo Merge collector (part of a Turbo exhaust manifold for anyone wondering)
Took about 6 hours and was actually quite hard! marking and cutting the weird angles with nothing but a Angle grinder, I wish I had a Bandsaw! (adds to shopping list)

are the merge angles set at a specific angle?

Welds look a little cold
Im still really quite new to welding... should they be sitting a little flatter? I just used the chart on the welder to choose the welder settings (for 3mm steel)
The hardest bit was definitely marking the cut lines accurately? anyone got any tips on how to do this? I basically just lined the lines on the wooden base up with eye and drew em on with a marker... I sussed out how to cut them straight by the end tho, But still a bandsaw or maybe even a drop saw with an adjustable clamp would be handy..

In reguards to penetration, heres a question for ya... I had the welder setup for 3mm but as you can see in the following pic when you cut the steel at and angle some sections end up being thicker then 3mm? So Should I turn the welder up for these areas?

Also, where the pipes/metal butts together, grind the sharp edge off, that way when you put the two joins together (before welding) you shuld see a trench where the weld will fill in.

Anything else i add will just become technical gibberish

Welding pipe in position is seldom a sucessfull [ie, super neat] process with the mig.more info please Col, as i have always said you can never have enough knowledge
The reasoning is....in order to do the vert, starting around 19v, then by the time you get to the top 21v is better,....but...see?..... technical giberish! This could go on for pages! I cbf!
All i will add is....practice, practice, practice.
oh!...& don't weld over your tacks without grinding them first...if you want a smick finish.
I would slap my apprentice for doing that!

As long as you have burnt both edges and theres no porosity it will hold together for the job required, Try grind stop starts as mentioned and always weld down hand were praticle.
making a developement for a three into one is not an easy job but you look to have done a nice job.
What is on the plans now for your next sicky.

Cheers its actually a 4 into 1, just cant see the rear leg in the pic
I think this is probably wrong but as you can see I did little tacks one after another which gives it more of a TIG weld look (I know im still too messy to be comparing it to a good tig weld) but yea... Should I be trying to do continuous welds rather then a row of Tacks?
Next... well I just picked up a bunch of steam pipe bends so will be making the rest of the manifold when I get a chance.

once you have the item tacked up good continuous welds are better but depending on the size of the item and heat input required , more heat more distortion.
