Nothing on you but a full ghillie suit and spoiled meat or broth of enlightenment, full out crawl from distance commando style, can be done without bug repellent. Take it slow and pray you don't touch them.
Easiest and safest way to tame this is to lure it under water. They stop aggro and you can tame as you please. Just make sure you come up for air every once in a while. Also be sure the water is deep enough.
Taming is pretty straightforward. Soothing balm and broth of enlightenment. Fully set of ghille armour and consume a bug repellant. Go up to the arthro just enough to feed the broth and then stay still and don’t touch anything and soon you’ll have a metal destroying tank
