 Please note, the induction only covers the basics and essential safety elements, as well as any hackspace-specific rules. There won't be anything on welding techniques / settings, as there's a myriad of information online.  Please note, the induction only covers the basics and essential safety elements, as well as any hackspace-specific rules.

 +__Gas vs Gasless welding__
  
-=== Gas vs Gasless welding=== 
 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. 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 Whilst the welder can operate as a standard MIG (ie with Gas) the Hackspace does permit compressed cylinders.

 +__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

 +===== 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
