Test panel

[Jay Hicks]

Hi guys,
I’ve done a few quick test tack welds, on the rear quarter panel that’s coming off, what one do you think is near the mark (if any) I’m using a Clarke mig 130 en
It doesn’t have much in the way of settings. W/s is wire speed, it has min 1 or 2 and max 1 or 2, I’m using Argon gas, 0.8 wire.
I think anything on max will burn through on thinner stuff? and I’d say wire speed around 5 seems the sweet spot. Many thanks

Do you have the manual for the welder? For my Clarke it gives the setting for steel as between 5 and 6 for steel(I think), which is a very narrow range.

I suppose this allows for other materials.

But if I stick between the suggested ranges it works very well, so they might know what they are doing!

I do have the manual, it says min 1 w/s 5, it just looks like a bit too much weld but probably my technique, I’ll keep practicing of course and tweaking as I go.

All the soot looks like you have a gas coverage issue. You mention Argon gas above - pure Argon is used for TIG welding - MIG welding would require either pure CO2 or a CO2 blend.
What kind of gas cylinders are you using? Disposable ones or a big cylinder?

Hi,
I’m using a large cylinder of.. Hobbyweld 5 (copied from there website) is a unique blend of Argon, Carbon Dioxide and Oxygen gas mix (often referred to as a tri-mix or an argon shield).
It does say it’s perfect for mig welding thin metal? thank you.
