welding upside down advice please
I've notched out a rear chassis cross member to accept a raised flange on my fuel tank - long story! Anyway I'm pleased with my MIG
welding results on the bench but today tried welding the underside of said chassis member. Its a bit awkward and reasonably reachable but the welds
aren't as good even taking into account I'm not as close to see as on the bench.
Should I alter the wire speed or gas or other setting?
Or should I just try harder and practice more?
Thanks in advance for any advice.
Ian

The wire speed will need turning up or it will burn back to the tip dont hold the gun 90% to what your welding or it will fill the nozzle with
splatter hold it about 45%

Don't know about improving the welding but if wearing overalls then lacy bands round the sleeves stop the red hot bits going down. It really
hurts  especially when it causes you to move you arm and stab yourself in the hand with the red hot wire feed.

Wear those little foam internal ear defenders, nothing to do with loud noises!
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

Use a welding glove and shield the shroud with your hand to catch as much of the spatter as you can...it does and will go everywhere and in the lug
holes hurts like you won't believe....feels like a mad bee in yer lughole

Wait 'til you "just doing a tack, so don't need to put my gloves on" and a big gob of molten metal jumps off (oh, the joys of
gasless wire) and lodges between your watch and your wrist.
I think I invented some new words that day.

Hmmm...
Done the "fiz fiz fiz fiz fizzel " resulting as a series of burns down the fore-arm and a bigger one on the elbow. Even had one go as far
as my arm-pit and the down the chest/belly-button variation and the buzz in the ear.
Wear gauntlets pulled over your slieves and do up your overalls to the neck. Lots of light on the job helps as the job is rarley as well lit when
working uphill.

This reminds me of when I got weld spatter into my boots. The first time I tried getting them off ......... after that I learnt to accept by the time
i've undone the laces it will have cooled. Instead I just burn and try not to swear so loud the young kids next door hear (or hop like a fool as
they already think youre the strange neighbour).
As for 'how to' I second the advice given.

Get yourself a pair of hotsleeves and a welding hat from someone like Frosts a welding apron helps as do a pair of normal googles as well as a welding
mask. I tend to find turning up the welding voltage helps when welding upside down .
