Arc welding roll cage?

[BlitzK5]

Im currently making a roll cage and Im getting my dad to do the welding. He is good at it. I was just wondering if there is a disadvantage to using the arc instead of a mig? Will the strength of the welds be the same.?

If he's good at welding it shouldn't be a problem. If you're not sure you could always do a couple of test runs on scrap tube and post pics.

If he can arc well, it'll be just fine.

i would sudgest a 7018 rod, or a different 70** rod. they are stronger than most rods that people use. unless he has a stronger rod above 70, go with it.

Yeah thats the rod thats being used. Thanks

Mig welding is one of the hardest processes to master- I say master because anybody can lay down a bead, but to get a GOOD MIG wled takes practice. I would prefer stick on any heavy steels

Unless the cage will be welded outside the vehicle where you can flip it over, I would suggest a faster freezing rod for the overheads portions.
