Hi everyone and thank you for the further comments. Yes, it was a gas problem! Cock-up at the filling plant apparently and I received 100% Argon instead of 82/18 mix. All sorted now and great looking beads.

if you check them out on ebay you'll find 8L bottles, you keep the...
Yeah, it's more or less a pool within a pool isn't it. I'll be chuffed if it turns out to be gas, but I won't be broken-hearted if I have to use stick, there's the debate that stick may be stronger, but I'm not sure that's applicable to 3mm. I just thought that it was about time I got on board...
Thanks, but yes, it's the correct wire setting. Everything is set right - I've reset it a few times to the correct synergy settings, then tried running a few beads before tweeking the voltage, amps and inductance, but always the same result. It really is looking very much like a gas fault...
That's a great help thank you. I did similar but the results were nowhere near as night and day as that. I'm beginning to suspect gas - as suggested by an earlier commenter. I looked at a few vids online after the comment about pure Argon and the sound of the arc, the soot and spatter are...
It's a synergy machine, interestingly when I dialed it all in the machine set everything the same as a chart I found online (125A 19V for 3mm) so I've upped the voltage as far as 20.5 to make the bead wider, but it stays the same
Sorry don't know the product name of the gas. I'm in France at the moment and you can only get gas on a contract here, it's really expensive so I'm buying it in from Poland - reputable company selling to the welding & engineering market.
Thanks for the suggestion, I've played around with my travel speed and yes, I was travelling way too slow for MIG at first, but I think that I have it about right just now. I've tried different 'weaves' - small circles; back and forward; small arcs; they make a minor difference to the...
Thanks for the response, I'll try to take some pics in a moment. Everything cleaned and brought up to a shiny finish with a flap disc, doesn't make any difference if I weld on a flat piece of steel or a fillet, the bead looks roughly the same.
Hi Guys, I'm a fairly experienced MMA welder trying to learn MIG. I've a big project using 3mm x 100 x 100 box section and I'd like to use MIG, but struggling with the bead sitting too high on most welds. The material welds fine with MMA with GYS 2.5 6013's @ 65A and Force set at 5 /10....I...
I need to weld several brackets onto one side of a 5m length of 100 x 100 x 3mm for a large framework, there are 10 to do. I've done similar projects with shorter lengths of the same stock and I used clamps and pretensioned on the opposite side with a bit of bend. In that instance I got away...
Mains feed and connections are fine. This afternoon I noticed that the wire was sloppy in the contact tip, a vernier showed the sealey wire to be 0.8 so I changed the Sealey tip to a 0.8 and the problem went away. The Sealey wire isn't great though, slag is really hard to remove so I've...
Really interesting!!! I'm a newby to the forum and was unaware of the Sealey section, but I posted a similar problem in the mig forum. I was welding fine on the wire SUPPLIED with the MM 100 but things started to go belly-up half way down the roll. When the roll ran out I put on a new roll of...
Thanks for your response. Clamp and tip are tight. When the problem first occured I changed the tip for a new Sealey 1.0 but it made no difference. The problem got progressively worse without any changes to work materials or other elements although the change of wire reel appeared to increase...
I'm having a problem with a Mighty Mig 100. It's 1 month old and I'm stuck in France, hence I can't take it back under warranty just yet.
It was welding great on the supplied wire but started losing the arc causing the wire to push the torch away from the workpiece. The fault is random and...
Thank you everyone for your advice & suggestions, and thanks Rannsachair for the link - what a great idea that is, I've never seen anything so 'to the point' for welding.
