Line 2: <div id="level1"></div> == TIG welder induction (TIG Mode) Level 1 == Level 1 induction in intended to cover the basics of how to use the [[Tools/TIG\|TIG welder]], it covers basic safety information and how to use the welder effectively on mild and stainless steel in positions 1G and 2G/F. It is strongly recommended that people undertake [[Tools/EMP235ic\|MIG]] [[Tools/mig/induction\|induction]] and practice it thoroughly before attempting TIG welding, that said you can start welding straight away with TIG but it's likely to take considerably longer to develop the required skill to use it effectively. People undertaking TIG induction need to have overalls or other non-flammable clothing that covers all exposed skin except for head and hands. Wear stout shoes or boots, no open shoes allowed. If you have any metal you'd like to practice on then please bring it with you so long as it's plain steel with no galvanized coating or paint but if you don't have any then we usually have suitable scrap around to practice on. There's no charge specifically for the level 1 induction but normal welder usage charges apply, you should expect it to cost around £10 for the induction and a bit more if you spend some time practicing afterwards which is strongly recommended. This induction may takes up to 3 hours depending on skill. Please remember that what you might have seen on youtube/instagram is people showing off their very best welds that may have taken years of practice and multiple attempts to achieve, you will NOT be getting results like that after just an induction. The goal for induction is to be able to use the TIG welding without being a danger to yourself or others, it's not even to achieve structurally sound welds, TIG welding is a high-skilled process and it takes a minimum of hundreds of hours of practice to get photograph-worthy results like that. {\| class="wikitable" Line 29: Using an auto-darkening welding mask Suitable settings on mask (9-11, 12 maybe - start at 10 and adjust) * Testing visors before use * Any setting will save your vision, you're just adjusting for best visibility ** Shouting "Eyes" * PPE - Overalls, stout shoes, gloves, mask, dust protection when needed, Cover all exposed skin or you'll regret it! Line 141 ⟶ 143: Types and their suitability * 2% Thoriated (Red Tip) - DC Welding on steels only, radiation danger * 1.5% Lanthanated (Gold Tip) - DC Welding, Good on copper/brass/nickle/titanium/high-alloy stainless * 2% Lanthanated (Blue Tip) - Universal, can be used on all metals and polarities, recommended for normal use *** 2% Ceriated (Grey Tip) - DC use on thin materials, excellent arc stability at low powers Line 158 ⟶ 159: * Welder Checking correct polarity, making sure earth lead is connected to work Check tightness of connectors, they'll catch fire if they're loose! ** Plug in welder but don't turn on yet. Directly plug in, never use extension leads * Gas Check remaining gas level Connecting cylinder ** Setting suitable gas flow rate using ~~both~~the ~~bottles~~bottle's regulator using the table on the welder, but consider situation of weld \|\| Suitable setup and settings for executing the weld Line 258 ⟶ 259: \| Travel too fast \|\| Gaps/thin spots in bead \|\| Fast movement has pulled the bead forward faster than the welder could melt the material \|} \|\| ~~Recognising~~Recognizing faults and knowing how to fix them \|- \| ~~Practising~~Practicing a steady bead \|\| Inductee practices moving the puddle on flat stock till competent (may take a lot of time and re-grinding) \|\| Getting the basics right \|- \| Laying a bead using filler \|\| Line 280 ⟶ 281: [Inductee practices laying a filler bead] \|\| Laying a bead while using filler \|} Depending on how things are going and the amount of time available the induction can stop here and allow the inductees to practice welding until they're comfortable with reflow and filler beads. The induction can resume on another day to complete the training on how to actually join metal together. If so the "Shutting down and cleaning up" section below should also be covered. {\| class="wikitable" \|- ! Topic !! Detailed contents !! Rationale \|- \| Butt joints \|\|
