+Please only use the equipment and materials covered in the induction. Please do not use your own equipment. The welding / hot works area is a trial, to prove to our insurers etc that we can have a hot works area without burning the hackspace down

 Prior to using the welder, you must attend an in-person induction. Please post on the forum if you want an induction. Should be starting spring 2025
-Prior to an induction, please have a quick read through the welder manual, and read this wiki page. There is PPE provided, however the risk assessment requires that inductees bring their own respirator to protect from fumes

 The welder is designed for both gas MIG and Gasless welding, however in the Hackspace all welding shall be the gasless type. This uses wire with a flux core to prevent oxidisation and contamination of the weld pool.
-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

 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.

+This extractor is intended only for welding use, and not general extraction / cleaning tasks. However prior to welding, empty the contents of the extractor into the general waste bin, **before** starting any welding activity
+===Avoiding bin fires===
+The standard general waste dustbin potentially contain flammable materials, and therefore care must be taken to avoid invertedly disposing of hot embers, sparks etc, where they could later ignite. Placing hot items in the normal bin poses a fire risk
+Therefore, a separate "welding dustbin" is provided. It is a standard steel dustbin without a bin liner, so is generally fireproof. Is solely for disposal of any waste which may be hot and pose a fire risk. For example, arisings from sweeping up, after welding.
+Signage attempts to prevent its use as a normal bin, but experience shows signage is ignored, so there may be flammable items already in the bin. Before starting any welding tasks, empty the dustbin into the general waste bin.
+Using this bin acts as a stop-gap, allowing time for any hot objects to cool down.
+===== Consumables =====
+The following items will be stored in the welder, as consumables
+  * 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
