 Please note, this is a work in progress. Please do not use the welder until inducted - thanks, Ollie

   * Welding hood or mask. There are three hanging up, just outside the hot works area. Link to manual [[https://www.clarkeservice.co.uk/manuals/welding_accessories/PG4_Headshield_Iss_3.pdf]]
   * Closed footwear
+  * The risk assessment also specifies a respirator, to protect from fumes
 These are the minimum requirements. You may also need additional PPE for other related tasks, such as eye protection when using an angle grinder.

+__Welder settings__
+Review the manual for a table showing recommended gas settings. Additional trial and error will be required to get the right setting.

 Whilst the welder can operate as a standard MIG (ie with Gas) the Hackspace does permit compressed cylinders. The risk assessment for the welding has not considered the use of shielding gas, so for the foreseeable, all welding shall be gasless
+__Welder polarity__
+The welder should remain in the "no gas" configuration. The torch is connected to the negative terminal (-ve), with the earthing cable connected to the positive (+ve) terminal.
+__Loading wire__
+The welder manual explains this best, however it will be shown in the induction
 ===Fume extractor===
-The fume extractor is an Extractability Protectavac by Weldability. It must be used at all times during welding, to help keep fume levels low

+===== Consumables =====
+The following items will be proposed, for inclusion on the consumable list. Wire and tips will be required frequently, however torch shrouds shouldn't need replacement often
+//For the time being, I'll provide wire and tips, just to get inductions started - Ollie//
+  * Welding wire. Flux cored "gasless" wire, 0.8mm diameter, 0.45kg reel. [[https://www.toolstation.com/sip-mig-gasless-flux-cord-welding-wire/p13760]] or similar
+  * Welding torch tips. 0.8mm diameter, pack of 5. [[https://www.toolstation.com/sip-mig-contact-tips-08mm/p96874]] or similar
+  * Welding torch shroud. [[https://www.toolstation.com/sip-conical-mig-shrouds/p11948]] or similar
