china 40w laser machine power lead for UK or Ireland

Standard "C13" IEC sockets are rated to 10A, only (the kettle-type are a different variant - "C15", by memory, though I might be wrong - and have mechanical interlocks to avoid the wrong plug/socket combos); So, standard PC-type leads should be protected at no more than 10A. In reality, I can't imagine the wiring inside the unit to be rated at that level - a visual should confirm. I'd be tempted to replace the fuse with a 3A.

Bonding straps?, just crimp a couple of eyelets onto the ends of some 2.5mm stranded copper wire with yellow/green insulation and bolt from a single star-point bolt fixed through the steel chassis (look to see if the ground stud provides a suitable earth), the other end onto each hinged/bolted panel (so, main lid, the removable control panel lid, and maybe the rear laser enclosure lid), having cleaned the paint off the steelwork on each panel (don't rely on the bolt to provide low-resistance path to the panel), tighten, then if you fancy, a dab of hammerite over the top to stop corrosion.

Of course, you're reverse engineering safety into the machine - for all my ramblings about these, if I'm honest, I normally live with the flaws.

Thanks doddy,very helpful
Some pics of inside to see if things look ok. Still some bits of foam and other packing i still have to remove

Ah, brings it all back to me. Just thinking of a couple of the mods I did - I removed the curly airline and replaced with soft silicon, encased in a minature energy chain bolted to the inside of the front panel - just to avoid it getting tangled in the X/Y axis - There might be better ways to do this. Also, I 3d-printed a bracket to hold a single-axis red laser-line diode, centred on the final mirror, so that you get X/Y centre lines on the material under the mirror (you can't use a X/Ycross-hair diode, like I tried first, because the projected beam position is affected by the height of the material being cut)

Yea i just noticed the position of the laser dot would move with different material, I planned my air assist and dot to go together untill i noticed this so i might get the air assist and laser-dot from lightobject because i think that dot stays in the same line as the laser.
