How to TIG Weld Aluminum and Get the Stack of Dimes Look, Even With an Old TIG Welding Machine - 0 views

  - Length of the Arc-find that spot where the arc will be close enough to do the job and time will be spent using the gas welder and not preparing electrodes.
  
  - Filler rod size- As well huge of a rod can quit the shielding force of the gas and serious heat will be lost from the puddle. A rod that is too small and the rod will just melt before it makes it to the puddle.
  
  - Use a stainless steel wire brush-not carbon steel. It will conserve a lot of headaches later
  
  If you devote some time watching out for some of the TIG welding "Gotchas", you will conserve time and cash.
  
  A single of the items you find out if you have a small Miller Dynasty 200 a/c d/c inverter Tig welder is how to do welding on thick aluminum castings with less amperage. I have had the chance to weld with two truly well-known Tig welding inverters that are capable of Tig welding aluminum utilizing 115v or 230v power the Miller Dynasty 200dx and the Lincoln Invertec v205t. Both machines are high quality power sources but each of these welding machines are limited to around 200 amps output. Being limited to 200 amps makes you weld smarter not hotter. Instead of just setting the amperage to 275 and plowing ahead like you would on a heavy duty Tig Welding Machine, you have to use your head. Preheating thick aluminum parts is a proven way to minimize the amperage needed to weld. But when you are in your garage and do not have access to a heat treat furnace or oxy-fuel torch, how do you preheat? Well, right here are a handful of tricks I have learned:
  
  Use a gas grill. But make sure the aluminum portion to be welded does not contain anything at all damaging that is going to taint the burgers you may want to cook next week. (It would actually be a excellent concept to have a cheap grill devoted for preheating aluminum parts)
  
  Wrap the part in aluminum foil and location it on the stove on medium heat till the heat conducts via the portion. (About a single or two beers later the part will be warm sufficient to weld)
  
  Use a little propane torch and preserve it moving until the portion is hot sufficient. (Just hot adequate to sizzle spit should be ok.)
  
  An additional tip for lowering the amperage necessary to Tig weld aluminum is to use a 50/50 or 80/20 argon/helium gas mix. The added helium truly makes a difference. Not only will you require less amperage, but the aluminum will puddle quicker and cleaner than with pure argon. Trust me on this one!
  
  Lastly, I recommend using as tiny a Tig cup as possible. Some folks refer to them as Tig welding nozzles but in any case it is the ceramic tip that goes on the end of the Tig torch that directs the shielding gas to the weld and protects the tungsten electrode from becoming oxidized. Using a tiny Tig cup requires much less shielding gas. aluminium tig welding, tig aluminium welding, best tig welderMost folks assume that TIG welding anodized aluminum is just like welding any other aluminum piping.
