hi guys
so the latest addition after my plasma cutter (boy how i ever did any cutting before that i dont know!)
Rtech 161 acdc TIG
so have been trying to build a die sor a sealy manual bender to bend 25mm x 25mm x 1.5mm ally box section at 90deg but i haven't got any stock of the correct size so...
i got the grinder and a cutting disk and made slots until i could bend it around the 90 i wanted.
then got the tig out, followed my limited info on using it
argon at 6 L pm
amperage base 80a (with the pedal it fluctuates between 30-80)
ac freq i found easyer to controll at 50hz
balance is set to 70% ish
not using the pulse feature as i want to learn first
oh and foot pedal
i have got 2.4mm filler rods
i cant remember what size tungsten size
and the little torch wp9 i think its called
so the gap left over where there is no box. when i start i seem to have to be really carefull or i blow a hole and then have to slowly fill the hole in, its not pretty and this will be on display so im going to have to clean it up and run some nice dimes over the top
also my arc is irratic.. grinding to a point and then just nipping the end off is this right?
any tips on welding such thin material?
thanks in advance guys
will post some pics tomorrow (before i get the flappy disk and candle out!)
