upside down welding

[bigwillyz]

hi

when welding upside down is it best to turn the
wire speed up slightly and turn the heat down a bit?

i know its best not to weld upside down but sometimes
you just have too

thanks mike

By 'heat' I assume you mean Voltage?

Amps/Current (heat) is wirespeed with mig welding. If you want more amps you must increase the wirespeed, less wirespeed, less amps.

In some cases it is advisable to reduce parameters slightly when welding out of position, but its impossible to say by how much because its all dependant on the specific application.

Can you give us anymore info on what your application is??

i was making a frame to go around winch on a 4x4 this
afternoon not being used for pulling,towing etc

its just when i was welding the top section on it started to droop
so i upped the wirespeed a bit and it seemed to weld alot nicer

so was just asking the quesion if that was the thing to do
or is it something you do to suit your welding style?

ive not come accross this problem before could it have been the angle you held the torch causing the mig wire to be trapped is your liner clean try blowing it out with compressed air (wire removed obviously) i dont think its to do with being upside down more to do with your machine
