Anytime the pool approaches the tip, it means you need to speed up the feed. In the case of overhead welding, you need to counteract gravity to keep the wetted metal up.
thanks mate any idea how much i should turn up...? i think i was on 5-6 ish so wat 7-8 ?
i was confused when i saw it happening as that was my 1st overhead welding with gas, never had a trouble with that before with gasless? maybe because it was soo underpowered i had the feed very high to get some penetration lol
Vertical, to go up you need to turn power and wire both pretty low. Not much point on 3mm<, youll just keep blowing holes through it. Anything thinner than 3mm just weld downwards, turn the wire and power down slightly.
Depending on what your doing you can happily weld much thicker in the downward direction, but not ideal if its a crital/structural weld.
As you weld the joint, if the weld trys to overtake the torch or you end up with a big blob at the bottom, that means your still running a bit too hot.
In an overhead situation i normally turn the power down fractionally, but the wire fractionally higher. Too much and youl end up with masses of sparks falling on you.
