## Description of the bug
The Z7 miner helmet has a welding visor which, when toggled, appends a broken sprite to the playe resulting in the funny clown overlay appearing on the player. This is likely unintentional.

## What's the difference with what should have happened?
The visor should have either no sprite or a dedicated sprite, not the funny placeholder.

## How do we reproduce this bug?
Spawn the Z7 miner helmet.
Use the inbuilt welding visor.
See placeholder sprite.
