Thread: to all you TIG welders...

Tweet

strike an arc on a scratch plate using DC+ (reverse) and watch your tungsten ball up real nice and pretty......switch back to AC and strike your arc. Aluminum takes a second to warm up so be patient. shiny surface is the key, if you pass shiny and go straight to dull you have contaminated your puddle. Remember to angle torch head in the direction of travel and to add consistent amounts of filler. Your filler may alos be too large and by the time the puddle is ready to accept it you are too hot. Double check your set up. Lincoln electric has some nice tech on their site and they also sell a slide rule chart to estimate your set up.

I'm not a tig welder but i thought i might through this out while your on the subject...

I had a guy weld up a new aluminum oil tank for my custom motorcycle and man did he ever lay down some pretty welds!!! Dimes as someone said..but to the point! what about "purge" the welds...sure looks nice on the back side as if it was welded from that side.. an other guy was doing my welding and it was peppered and even the stainless dose the same from what i've seen...I hope i never lost this welder OR i'd never see things the same

I wished i still had the pics on the inside..
