getting there but need help

breezer · Mar 8, 2009

Hi all,

I'm using a clarke 151en (gassless at the moment) to weld some 25 x 25 x 0.9mm box section into a couple of scooter engine stands.

It's not going so bad although the reccommended settings in the book are ridiculous - blowing holes all over, so I've reduced the power & wire speed down to a setting that works well. Lowest power setting & wire speed of 4

The problems I'm having are:

Still occasionally blowing holes as I get to the end of the box (I've been using the pull technique, but have been told I should really be pushing???) :dontknow:

Welding inside a 90 degree angle, there's obviously a technique for this, but at the moment I'm struggling to get a join, I just seem to be laying a load of splatter on one side or the other :doh:

any tips gratefully received I'm very new to all this.

Jim

I haven't done much flux core, you should be dragging tho.............

sorry I'm new to the terminology as well - is dragging the same as pushing or pulling?

I'm starting here . with the torch at this angle / and moving this way >

is that right or wrong?

Cheers

with a gas setup you should be pushing the torch so theres maximum gas coverage like this <--/ but with flux core i reckon it wouldent matter which way your going

ps for the fillet (inside angle) if your struggling, try weaving up and down while moving along, and if your still blowing holes turn the power down more but if your still blowing after that then move a bit faster with the torch, or is it because of uneven gaps? if its because of the gaps try putting tacks over them to fill them and then do a proper weld over it

To start with it was uneven gaps, but sorted that. Evo rage 3 sliding mitre saw... (nice)

I'll try pushing as it'll be a good habit to get into.

I wonder if the fillet would be better with more wire speed - think it's to do with not being able to get the torch in far enough and a lot of the wire is burning back? So as I move up and down it makes an arc when it hits the sides, but it's not getting right into the join...

Whaddya think?

Try welding right to left << / you can at least see where you are going

long as your right handed :whistle:
