Thank you so much. The best advice I have heard on welding car bodies! I put your advice into practice today and, what a difference. Solid, neat welds with good penetration and, never blew a single hole! It has given me so much confidence to press on with my project. Thanks again. 👍

Hi, this is good to hear. Which Amp setting did you use?

@ernied3123 28 дней назад

I’m a beginner and I’ve watched a lot of videos but I just learnt the most from yours in a fraction of the time I wasted on the others. Thanks so much.

@SolarTara 3 месяца назад

I started welding on my car this year. I had watched a ton of video, and basically it all boiled down to using the lower settings to get my welds, but so many preached tack / stitch welding. Well instinctively as I got on with the car, I started turning up the settings because I noticed it wasn't giving good penetration at all.. Finally, a video that puts it into perspective and confirms what I was doing. Thank you for this! I wish more people mention this

Thank you so much. I've been trying ways to get my welds to run much cooler, because of the mentioned hole blowing, only to end up with big lumpy welds. Never occurred to me to crank it up a bit as you just showed. I shall give it a try tomorrow. Lots of rust patches to weld in.

Wish I had watched this sooner. Just nearing the end of my first project welding and it was sheet metal. I ran into using too cold of settings. Getting huge mountains and they didn't even penetrate! Grind down and find id have to weld again but I had grinded the parent metal thin removing the welds. So then I got blown through! All that being said this is a great video I wished I watched sooner.

@jackrichards1863 11 месяцев назад

I often dont touch settings. Until i got a synergic mig. It's great to see this, which confirmed a notion I had that it doesn't matter much. Now I'm considering it may be an actual improvement. When i first welded all we had was arc. I learned a lot from repairing the ageing exhaustt systems with an arc welder and large rods. Once a mate got a mig i went and got one myself. Of course its a lot more user friendly and old exhaust pipe gets thrown in the scrap now. Japanese car panels are stil a challenge.

@michaelberry3094 9 месяцев назад

I am about to start welding some Japanese car panels myself. If you would share- in what way do you find them to be challenging?

@alankepler3124 4 месяца назад

Sorry my english is not so good. Do you mean that a Sinergic Mig is a better option to practice this tip?. Or did I misunderstand? . Or it doesn't matter if it is synergic or manual, and only the technique of this tip matters?. Thanks. Greetings.

That was really informative, i got taught to use the stick welder as an apprentice But these mig machine are a world apart, need to get sone practise in with mine Andcusing more heat is good sense,remember people with the stick welder using to low a setting and getting stuck

@gorporpio 5 месяцев назад

Excellent

@neilgarrad4931 11 месяцев назад

Thanks

@AXNJXN1 4 месяца назад

Well done. Mutually, when Flux Core welding, I also keep the voltage lower and nearly twice the wire speed feed. It provides the correct balance of 'excess' metal to heat ratio, preventing blow through and keeps the base metal cooler. I have found FC welding is just as advantageous for this welding, minus the slag but for the 'budget' welder, you can get this done too! Just need to figure out your particular machine and it's settings. Point being, FC machines can do this job, period, just learn it well. Cheers.

Great advice. Getting much better results after doing this and switching to .6 wire, but I'm not getting all that great of a penetration. Do you think I should swap back to 0.8 or maybe try some different settings?

@dynamicvehicleservices8170 11 месяцев назад

Hate having to grind thin stuff just thins it out even more

@StewSims Месяц назад

Good video and it seems to have done well. Have you thought about doing a video on a small car rust repair from start to finish? Lots of us have probably fairly poorly slapped a patch on something, but few have learnt how to do it properly from a professional like yourself (e.g. avoiding the need for too much grinding, welding and filling). Would be interesting to see how you'd tackle it and hopefully pick up some basic fabrication and welding tips and tricks.

@Urchfab Месяц назад

There's a video in my how too playlist. its old but should help you out. Cheers

@mfwwhelan7561 11 месяцев назад

Interesting video. Sometimes I get a vertical tail sitting on the top of my spot welds. It happens periodically and is not present on all welds. All my settings are unchanged.I asked a lot of people but no one has the answer, My welder is an ESAB Caddy 200Amp. I'm using the usual Argon/Co2 mix. Generally I use 18 Volts and 5m wire speed. Wire is 0.8mm. Thanks, Mike

Try turning the burn back down if you can adjust it. If not try holding the torch a little further away.

Hi, thanks for this. Which Amp settings did you use for welding the 0.8mm steel? My Welder has a digital display for Amps rather than the traditional 1-4 settings. Regards Joël

@JB-NZ 6 дней назад

@Urchfab Thanks for sharing this video. Query, do you have anything against 0.6mm wire for 0.8mm steel like on a classic mini? I had been using 0.8mm but changed to 0.6mm, and I am running a slightly higher voltage than recommended, but I think I need to turn it up further. Curious though how 0.6mm will compare to 0.8mm wire though and if it will react differently to higher voltage. Thanks

When you can't get to the back of the weld, is there a concern about the heat affected zone corroding quicker? Assuming using weld through primer is helpful if you can get it on to the back of the existing old metal?

@Urchfab 11 месяцев назад

Yes it’s an issue. Cavity wax or similar can be a good option for getting to the inside.

@rennkafer13 11 месяцев назад

Matt, are you able to planish those welds to account for shrinkage or do you need to TIG for that. I need to fill a sunroof hole in my Mini...

@rennkafer13 11 месяцев назад

@@NZMOPAR I know, my question was more about planishing MIG welds vs TIG welds and which would be Matts choice.

@Urchfab 11 месяцев назад

Mig welds are much harder so it’s more difficult so you need to grind off the excess material. Tig is softer but takes more skill on thin material.

@oikkuoek 11 месяцев назад

Any tips and tricks for welding an actual old, rusty and grimy panel? I tried to think of it, and I have never in my life welded two clean fresh sheets of any thickness onto each other. The panels needed welding have always been rusted through, and the patches have been parts of not yet rusted through panels of whatever sheet the metal skip has had to offer. Also, can you do that with a stick? Doing a rot repair when all you have is a stick and a box of slow fuses, in 4 inches of icy slush, trying not to burn the house down in the process.. Yeah.

Butt welding with flux core is next to impossible. Mig is nice when you have gas, but when you don't as in 9 out of ten times I've got my hands on one, it sucks. Not impossible, but sucks.

What sort of gap do you set up when butt welding panels? I've seen people weld with no gap at all, and some people who religiously open the gap up with a 1mm grinder disc as they go. I guess you don't need the gap if you're getting good penetration and no warping? I'm off to ebay now to find a block of copper. :)

Best to have no gap in my opinion.
