But without the purple cows & cuckoo clocks ! All joking aside dilute phosphoric acid & 25 > 30 volts works just fine & easily washes off & will not eat you ! thought i was the only one who used that , bought some carbon fiber yarn and some 14g wire and made up a brush i add some ci...

try welding with AC

contact this guy http://tatromachine.blogspot.com/


he has a lot of weld repair videos on YouTube as well

could be 17-4 ph

try a new collet , when they twist up like that the gas can be blocked


i'm guessing you don't have a flow meter ?

when I bought my two torches I got the 250 water cooled and the 130 gas cooled

that way I have both torches and both heads , gives me 130 , 150 gas cooled and 230 , 250 water cooled

it's been more then 30 years since the last time i made a custom cable i used to fray up the end and kind of smash it back down to look like a ball or mushroom then i would use silver solder to create a ball at the frayed end with all the frayed wires going in random directions it would make it impo...

that's the magnesium burning from lack of shielding gas

most likely the cup was too far away from the puddle

i think you will be better off building the entire corner back up with weld

being a restaurant prep sink ,it's probably already warped or soon will be

i'm guessing your showing the bottom of the sink i'd tap the seam back and tack then weld it up from the inside nope that is topside around the bowl!

try spot welding with a roller

Too tight of an arc and you will discover that instead of sticking your electrode into the puddle, the the puddle will jump into your electrode. It's like watching a magnet sweep up iron filings. That's why you'll see Jody lift his torch when dabbing filler wire, and move it ahead as he lowers it b...

looks like your having problems with the fillet welds in aluminum , I'm assuming 1/8 material thickness thing that have worked for me : number 5 cup 3/32 tungsten with 12 CFH , too much gas will steal heat from the puddle and if your at too much of an angle it will suck air into the weld tungsten gr...

duty cycle , on most machines , is how long you can weld in a 10 minute period

so if you have 50% duty cycle at 150 amps you can run 5 minutes ON 5 minutes OFF
