Welder settings r tech mig 180

[Jim Davey]

I don't know why more people don't mount the bottle horizontally at the bottom of the trolley if its a small one.

 

[Edwardbear]

Its got less distance to fall over then. Perfect sense

 

[Jim Davey]

Probably because strictly speaking gas cylinders 'should' be stored and used in the upright condition, but I'd be quite tempted to make a trolley that way if it were strictly for home/personal use.

You need to contact R-Tech.
I weld 1mm on those settings with full penetration, sometimes even blow through (operator error), you should see at least some, if not full penetration on 1.5mm using the same settings.

 

[Edwardbear]

How much gap behold there be between the old metal and the patch? I could be making the fit too tight then not getting and penetration

 

[Edwardbear]

Looking at some scrap I did a test on the weld is almost spherical on the outside of the sheer with zero penetration

 

[Swift&Bold]

Have you contacted R-Tech?
There's no point giving advice if your welder is defective.

 

[Edwardbear]

What do you thinks wrong with it. It's welding

 

[T0rnado69]

I don't really like the way you've fitted the welder into the trolley.

or having to lump the bottle out the cage when it needs changing.


and im sure they are plated steel.


would be worth a fair bit if completely stainless steel.

thats would be a lot of SS for a £1

 

[Edwardbear]

That is the only problem with the design. But I'm a thin strong lad so ill be fine. I did consider putting a hinge on the bottle part for easy removal but lack of hinge prompted a change of plan

 

[Swift&Bold]

What do you thinks wrong with it. It's welding

I have no idea.
You....will....have...to....speak....to....R-Tech.

 

[daleyd]

Pictures might help, and have you tried it on flat clean steel plate?

 

[Edwardbear]

I'm far too drunk to weld! Maybe tomorrow

 

[Edwardbear]

Had another go with lower wire and voltage. No holes so far fingers crossed. Bit concerned about penetration though.

I'm going to grind back and then fill in

 

[Edwardbear]

The problem I've got now is that if you look closely you can still see lots of holes. If I weld continuously over it all I'm concerned it will melt holes in it.

 

[Edwardbear]

How do I get my welds to look less like metal spheres and more like. Is it settings?

 

[Swift&Bold]

A combination of skill, experience, settings, technique and machine.
What did your welding course teach you?

 

[Edwardbear]

It taught me that I can weld bits of 5mm together in a variety of different positions. It didn't however teach me

How to set up my machine
What the different settings mean and how they affect the weld
etc etc

The course basically entailed turning up, the tutor setting up the welder and then saying you doing a lap joint today. I would then practice the lapjoint until it was perfect

The welds above are flatter but also wider than mine, not sure how to achieve this

 

[Edwardbear]

It was actually going reasonably well. Then I blew a fricking hole in it

 

[Edwardbear]

Did a bit of welding today. Wire tensioner turned up and what a difference. I may turn it up a little more just because it's not quite right but very nearly
