Re: Alu Mig noob disaster
Does the machine have a remote switch. If it does and its switched to on, then the volts set at the wire feeder. If its off then volt are at machine, Its a good guess based on other machine I use, not familar with your model.

Re: Alu Mig noob disaster
One knob is volts and the other is wire speed. If you have a machine that allows for wirefeeder volt adjustment. It wil be something like a switch that says local/remote. In remote the wire feeder controls volts as well, saves trips to welder to adjust. Wire brushing helps too. I avoid mig ally as t...

I have to ask, what do you think is the difference in the way they using the terms. One is iron powder the other is iron and oxygen, which also occurs when burning iron powder. I wonder if you didnt create question to just do an info dump. It is still widely used and to the best of my knowledge, Eng...

Re: Function of Iron Oxide in MMA Flux?
The iron powder not only melts in the heat of the arc to increase deposition rate but also enables the electrode to carry a higher welding current than a 'standard' electrode. The iron powder is electrically conducting, so allowing some of the welding current to pass through the coating. A quote fro...

Hi Rc, mate a 7018 is a low hyd stick. It is easier to get peno with a 6010 cause thats what those sticks are made for. If you can do a good job with 7018s all other sticks take way less practise.

Re: Help me Get my Oxy-Propane Cutting Torch Going
So oxy propane and oxy acet are similar, both are thermal cutting. They both heat steel to a glow and the you press lever and the centre hole is oxygen only, and it oxidizes the hot steel, in general kinda blows it away neatly. With both processes make sure that you light gas first. Turn gas knob on...

Re: How Much Metal to Leave on Tractor SSQA Mount?
Which hole the panel did you mean? It is generally a good idea to make it as 1 piece as you can, cutting the middle out of the panel can introduce stress points and would need welding, so extra work. And not much weight saving. Youtube one Looks like a backyard job but fair one. Ideally that top str...

Re: auto darkening helmet
Not knowing what you have, my guess is to find a battery and change it, or if it has a solar panel then sit it outside for a little bit. All helmets have sensors regardless of brand, and when exposed to welding light it activates the darkening lens, these sensors may be dirty or faulty. You may need...

Re: Dissimilar Metal Thickness
Yeah there is usually, while getting peno, you favour the thicker material slightly so you can burn into it and not terribly undercut the thinner material. It would help to do some practise runs and cut then to make sure you got it. Grind all areas you intend to weld clean. Even if you do out of pos...

Re: 7016 being smothered by slag
Some different sticks need slightly different techniques, that is usually not enough drag angle, going too slow for stick or too low amps. Both the more amps and a bit more angle force the slag back a bit more or going a bit quicker keeps it ahead of it. Either way it would only be a small adjustmen...

Re: HELP! Angle iron frame bowed and unsquare
This is one of those things with welding that is useful and horrible, when you get used to predicting. You can, using a stong clamp put packers under the edges and pull it down with the clamp. Its important to note that the bend moment needs to be found. For instance a beam that is 6 foot long and l...
