Thank you,
Yes welding galv steel emits extremely poisonous gasses.
I always wear a 3m respirator under my welding helmet and when I'm grinding too. The area to be welded has the galv surface ground off pre weld. Also with the garage door open and the back door, there is a good flow of fresh air too. I think welders used to drink milk to counter the Zinc fumes
so I borrowed this MIG from work
Hmm mig with Argoshield Universal BOC gas.
I really like this, and there is no Slag Inclusion.
The problem with inclusion for me is more long term, don't want it causing rust down the line, and a Land Rover needs rust like well enough said.
So the chassis can be welded by stick, bit it is too easy to blow a hole and cleaning the slag off much thicker metal is much easier.
So after many hours finding the right mig for me, and deciding not to go tig, beautiful although they weld.
I came across this ROHR 250 mi mig welder
Which has some interesting features.

IGBT MONOTUBES
The Röhr MIG-250MI has to be the most well-thought-out and complete MIG welder within its price range. There are so many little details here separating this product from its competition that you can start anywhere.
For one, there's the latest IGBT tech. Incorporating this bipolar transistor that uses an insulated gate electrode, the semi-conducting device gives you the field-effect transistors' easy control and the bipolar transistors' fast-switching and high breakdown voltage. At the same time, limiting electrical continuity, this tech makes the unit pretty much immune from short circuits.
Using ARC Force, the machine makes sure that the current is increased automatically when the arc gets shorter. Meanwhile, the Hot Start works wonders automatically boosting the tension at the arc's ignition of the arc, facilitating electrical arc ignition.
Of course, the product is about its high-end components as much as it is about these technologies/features. Incorporating inverters, this MIG welder increases its efficiency by 30 percent, drastically reducing the power required to weld and producing the most consistent power supply, making sure that the welding arc remains stable and secure.
Apart from that, the aforementioned IGBT monotubes increase the machine's efficiency too when you compare these tubes' performance to standard MOS tubing.
MIG AND MAG WELD
So I got one, and also got an Argoshield Light Cylinder from BOC.
After years of making a rod for my own back, using a 100A gasless mig which I now realise only went down to 80A on it's low setting lol
Can't wait to get a regulator tomorrow and get going :- )
