Cheers guys, that would kinda make sense them choosing the biggest bottles as to not to overdraw

So I've started a new job in a big fabrication factory and there's quite a lot of Oxy acetylene rigs all over. I've not had much experience with o/a but I'm confused with the withdrawal rate rules.... We only use the rigs for cutting and they are the biggest cylinders you can get here (320cf) I've b...

Alright mate, nah I'm only trying to master this as I want to take another test. I mainly weld thin gauge box/tube sheet metal. I do heavyer materials too but not as much and it's normally in flat position. I do alot of out of position welding on thin gauge work so getting it right on thicker first ...

I use 0.8mm wire (1/32) argoshield universal (Boc) think it's 12% co2 2% O2 and 86% argon it's recommended for material 4mm too 8mm I believe

Here's what it looks like

The dial on the left and right both work together on any of the terminals, I will have a Lil play again tomorrow morning. Ive used this machine for years but never gave this much thought as to what the difference is. I have a Miller dx 220 with I much prefer Thanks anyways guys

Heres the full front view

Have to wait till I go to work tomorrow but I can tell you now there's only two switches big volts small volts. The wire is fed from a separate rover

Hi guys, I'm still having some problems with vertical up mig. I use the right techniques (upsidown V) reduce power by 15-20%. The weld pool starts to undercut and crowning about a 3rd of the way up. If I turn it down anymore I feel there's gonna be lack of penetration. It's a bit hit and miss I have...

Here you go

Hi guys

I have this old machine at work that has three earth terminals on it. I normally have in plugged in to the one marked c. Have tried them all but not sure what the difference is?? Any ideas?

A Chandelier I made a year ago for some show in the west end. Not my best Tig work I have to say, the central Hub is made from Turned EN 1AL shite not nice to weld at all

Has anyone had the problem of the cup sticking to the job when walking the cup or sliding it along the join? If so what can be done to stop it?

You from the UK spokesy??

Thanks guys, will punt the hand switch back and practice using that. Thumb wheel control you say? What make of touch do you have trackranger??

Hi guys,

Bevel your flats and weld butt joins and mabe finish with outside corner? That's how I would tackle it. A good butt join is just as strong as a fillet!

Hi guys, new to the forum. Been in the welding trade for 6 to 7 years now. Mainly steel mig but doing alot more tig these days.
