From that picture, I would venture a guess that the cables are backwards(polarity needs to change). It appears to be just piling up on the surface and not penetrating at all. A two second squeeze of the trigger should provide you with a nice smooth little button of filler material melted into the ba...

It's not just you. My latest pair of glasses have progressive bifocals and they are very hard to find the sweet spot. I'm going to need longer arms or a telescope pretty soon.

Two machines!...Sweet, now you can weld with both hands...double the productivity!

We did a hyrdro test on a CO2 trailer. 450psi on a 300psi vessel. I've seen what just a few (less than ten)psi does when released in a hurry, I would not want to be standing beside that thing at 450psi...LOL Do those tanks make noise while being pressurized up that far? The creaking and groaning ma...

Got a call into the safety guy on the site to see what he deems appropriate before spend any money or effort on this. The rig has to be on their site tomorrow, so I'm hoping he'll return my call soon. I might even be able to get away with smaller cable than I proposed (0 vs 0000), saves me a few pen...

Travel speed generally dictates the size for a given machine setting, but...if you keep things consistent, you can manipulate the shape of the bead a couple of ways. First, more voltage will flatten the bead(make the puddle watery to that it flatten out), while more WFS(amps) will make it pile up an...

sorry guy's took a while to get back, tomorrow going down to the local welding shop to see if i can get a regulator for my argon bottle as in the few post's back the wire that's in the machine call's for gas so that might be a reason why my weld's are not getting any penatration correct?? Using sol...

LOL...that is funny, thanks for sharing.

Sweet! keep us posted

You can see I got a good 5-6mm of recessed tip. Should I be making the tip flush with the nozzle end... or just sticking out a couple o' millimetres? :) Do you have a Northern Tool over there or a local welding supply? I'm wondering if it uses the same contact tips as a lot of the welders over here...

That is way too much stick out for that small diameter wire. Is the nozzle pushed up onto the gun as far as it will go? You may end up having to grind the end of the nozzle back some(I never had to do that before). Well.... I say never, but to get close enough to the joint on a tight weldment, I did...

oooook.... stick out.... my contact tip sits quite deep in my nozzle (lol welding terms are sooo loaded with euphemisms) I simply screwed it in to the gun til it stopped. should I unscrew the CT til i get desirable stick out? You have it installed correctly if you screwed it in until it seated. The...

LOL...Len, I found that pdf and posted it too....in the other thread. Welding bear, Re-check your polarity and make sure it is correct for the wire you are using...that will also effect your penetration. I switched from a self-shielded fluxcore over to soild mig wire and forgot to change the leads a...

Good evening to you all and hope you're all well. I recently purchased the following MIG welder... https://www.machinemart.co.uk/shop/product/details/135te-turbo-mig-welder ...and have around about 3 hours' practise under my belt. Looking at making some items like a workbench before moving on to ca...

The only difference is how we attach to the machine. Usually we have a threaded hole or some sort of bung already there and it is easily installed and removed. Thanks for the reply....attaching to the rig, I figured the c-clamp style Tweco work clamp would make it easy to clamp and un-clamp from th...

Thinking about using a Tweco C-clamp style work clamp for the rig chassis, then a 10' 4/0 welding cable out to the 3/4" diam. ground rod with a split bolt to connect the cable to the rod.

thoughts?

So far adding up the parts looks like around $170 plus tax.

W B, Are you using 75/25 Argon/CO2 or 100% CO2 ? I'm no Mig expert but if I remember right 100% CO2 penetrates better than 75/25. There's plenty of others here who know way more about Mig than me and someone here can surely help you get to the cure. Len Hi Len, Not trying to be contrary...but in my...

Whatever I come up with, it needs to be something that a safety guru onsite will approve when he audits the rig.

Using correct terminology eliminates a lot of confusion when everyone is on the same page. I'm sure that will continue to use the wrong terms at times just out of sheer ignorance...LOL The field of welding encompasses so much that I doubt any one person can possible know it all in one life-time. Fac...

Hi guys, So. Went out this morning. 1.5mm steel. 45 degree bevels on each piece. Gapped. Welder on max. settings with a mid range of wire speed. Penetration much improved. But still not covering the join lines on the backside of the workpiece. i'll throw a few photos up in a few. Wonders what I'm d...

Welcome! From the quick web search I did, the sp100 runs MIG with shielding gas or flux core with no gas. If the last owner ran it with shielding gas then you'll need to change the machine's polarity from electrode positive to electrode negative. Not sure how it's done on that machine: it may be a ...

I've been tasked with grounding a mobile drill rig. I need to come up with a way to easily ground this piece of equipment while onsite inside a substation. I envision a work clamp that(c-clamp style like for a welding table) that can clamp to a copper lug bolted to the chassis of the rig and a 0000 ...

Im also using the 'loop to loop' technique to make them look pretty So I tried my first few butt welds. I tried with root gaps of varying thicknesses and still I can't get the penetration correct. I have looked online and it's definitely the case that you shouldn't be able to still see the join on ...

Welderess,
I replied to your PM, but I receive a message that you have your PM box set to not receive messages at this time.

Yes, I was teaching (new employees at my previous employer) and I (still) perform personnel Qualifications and Certifications for employers in my area as a TPI.
