Welding upside down

[MWP]

Hi all,

Well, im now stitch welding up the chassis on my RA28.

All is going ok (not pretty but the welds are strong) except for where i need to weld upside down.
The weld keeps pooling inside the tip of the MIG welder instead of on the steel im trying to weld.

Any tips?

Thanks!

maybe lower amps and wire speed?

The MIG only has 4 power levels.
Im on setting 2, if i go down to 1 the welds dont pentrate and i just end up with a bead on top of what im trying to join

sorry thats about as far as my welding knowledge goes i was welding something today on a car upside down, i just kinda stuck with it and welded on an angle so the molten drops could fall to the ground, enough of the weld stuck so i was happy of course i have lots of little red tracks down my arm from where little balls fell on my arm and rolled down

You know that there are also types of wire (edit: and shielding gases I think?) that you can't use upside down? All my info is at work though so I can't make any real suggestions, sorry.

have to change the metal transfer mechanism from dropping blobs to actualyl blowing the metal across with the arc...
can't remember how to do it, but if i set my welder (with same voltage and wire feed) to the "high power" capability setting (or whatever it is????) then it changes to work upside down

maybe higher voltage and wire speed and faster welding? try doing some vertical welds with different setting and see if you are transferring blobs or not (blobs = bad)

Tig or Oxyset would slove your problems

Im using Argoweld from BOC and an unknown wire (came with the welder).

Looks like ill just have to keep on experimenting with different settings.
Whats the bet ill get the hang of it just before the jobs finished

its all about practice mate get a few bits of scrap and play with your technique and power settings, also certain wires dont like positional welding, at work at the moment im using a 3xp flux core wire and its grate for poitional welding, comes out beautiful, you will find that certain wires just will not like it as the weld is too runny so too speak as your saying, its much like stick welding for instance an iron powered rod is only really good for down hand runs where as if you get a standard gp or low hydrogen rod which you can get too weld any position you like, with the right technique and power settings of coarse.

and ya i am a boilermaker

Which Argoshield? Argoshield Light, Universal, Heavy, 52? And is it Mild steel? What thickness? Example Argoshield Light for mild steel 1 - 4 mm, Argoshield Universal Mild Steel 4 - 12. Argoshield should only be used with mild though anything else should be a different shielding gas, Alushield, Stainshield etc otherwise the weld will have impurities in it.

But yeah more than likely you will have the hang of it soon

welding up side down in stead of doing a contious weld try running a line of stiches,
if done well it comes out nice and pretty like tig,

example of this method, not quite as pretty as tig but better than a normal wonky mig line
although i would do longer stiches to ensure penotration, as opposed to short tacks

[MWP]

Woah, that would have taken some time, i dont think i have the patience for that.

The gas is Argoshield Light which i guess is about right for car body work.
Im welding up most of the chassis with 1-2in weld, then a gap of 1-2in.

OK cool, if this is the wire you're using you should be able to use it upside down, as indicated by the little picture:

Higher voltage and wire speed generally lets you weld upside down a bit easier than with a lower voltage. Just have to be careful to work fast enough so that you dont blow holes through it. Try working faster along the inch, you will penetrate the metal quite quickly, so you just have to get a move on.
