The last heading that I posted was Burning Metal. After reading that topic you would have understood what it meant.
Well this time it is Sticking Metal and yes you guessed it I am on Stick welding and the stick keeps sticking to the metal when I try to spark up.
I have another week of practice with the stick welder then we move on to mig.
I was later told to turn up the amps and it should not stick. Well next week we shall see.
Christos. Just a tip mate, a welding rod is made up of 2 components ( basically ) a core and a flux. What happens is you make a contact with the core onto the metal at the wrong angle/pressure/speed and a couple of other wrongs and the flux breaks away from the core of the rod.
Without the flux ( the brittle coating on the rod ) the metal ( for want of a better word ) has no shielding, the flux of a arc rod is similar to the gas with MiG TiG without it you simply don't get a weld.
Try this, hold the rod at more of an angle then the instructor tells you and sort of strike the rod onto the work piece as you would strike a match, quick side strikes rather then a pressure point contact. You will see a long line of sparks as you draw the rod along the steel/work piece, now half way through one of these long strikes ( the length could be as little as 1 inch ) pause the rod and apply downward pressure, just a fraction and then lift the rod ( about 1/8 inch ) off the work piece, ( all this must be done as one action, sort of speak ), there should be a arc and you should be able to do a weld. all settings must be correct and the workpiece be clean and well earthed.
What you are doing is creating a dead short of an electrical component to cause extreme temperatures
Jumpy would know what I am trying to say.....
If you think welding mild steel with rods is sticky, try welding Stainless Steel with arc rods.
It helps to create an ark with more power but not needed once you get used to it. A rod with blue in it, full blue flux or striped blue and grey flux are better rods to learn with ( more friendly ).
MIG welding is a piece of cake compared with stick/arc welding.
Good luck.
