'Type 15' under the Euro-Torch section Liner will depend on if it's a Euro (screw-in) torch or direct wired - direct wired on yours I think so the Liners are different; order one anyway & I'll have the correct one sent (not yet listed in the shop).
Gas regulator depends on the gas you intend to use - CO2 or Argon/CO2 mix - different cylinder connections, both listed.
Same regulatorwas going to have a go at pure argon for alu but normally argon/co2 for mild steel
Nope.-is co2 better
You can but not always a straight forward fit & thick end of £100; service your existing torch (regularly) & it should perform fine. Also replace rusty wirecan you get euro torch conversion kits
Same regulator

Just 5Kg reels on that & the steel Liner will be a problem, think they only accept the PVC type.
