Hi Andy,

The reason i ask is because i already own an arc welder and loads of 2.5mm rods and im reasonable at welding with them, but its difficult to weld less than 2mm thick, which im guessing is why everyone recommends buying a mig welder. Im trying to cut down costs and 1 of the major expeditures was on a mig welder, which would be £200+, i've tried to find a cheap one but to no avail.

So i thought why not get rid of it and just increase the thickness of the steel box meaning i can just weld it with my trusty arc welder since there dont seem to be too many downsides that i can see, 1 being it adds an extra 20kg to the chassis and the other being it will cost another £30 for the steel.

Im just wondering if there are actually any major reasons im missing as to why 1.6mm thick tube was chosen, which would mean that 2.5mm thick tube would not be appropriate.
