What is the equivalent to MIG welding?
Flux-cored – Flux-cored Arc Welding (FCAW) Flux-cored arc welding is similar to MIG welding because both use continuous wire and power supplies. You will combine a continuous electrode with a base metal. The electrode is a hollow tube filled with flux that is fed through the weld gun and into the weld pool.
How do I know what size MIG nozzle to get?
Your goal in choosing both size and shape is to optimize gas coverage and reduce spatter. One method for finding the optimal nozzle is to choose the largest bore size possible in a shape that gives you the best access to the weld joint. Otherwise, you could run into issues with either job quality or nozzle life.
What is the flow rate for MIG welding?
So what is the correct gas flow rate for welding? The correct gas flow rate in MIG welding ranges between 15 to 25 CFH.
Why is MIG welder spitting?
A properly adjusted MIG welder should sound like it is frying up bacon when laying a bead. You want a nice sizzle with little “pops and spits”. The problem here is that the welding wire is coming out too fast for the surface you are welding on and the heat settings you are using.
Is MIG better than stick?
Stick welding is great for beginners because it’s easy to learn, and very affordable. In contrast, MIG welding is faster and more efficient, and cleaner than stick welding. However, MIG machines are more complicated to set up and learn, and are also usually more expensive.
Are MIG nozzles universal?
The types of MIG welding nozzles on the market are available in a range of sizes and shapes. Choosing one will depend on what the application is, the welding process that is being used and joint access. Typically you can get nozzles in slip-on or thread-on varieties, as well as heavy-duty or standard styles.
Are all MIG nozzles the same?
Most nozzles look alike on the outside but the inside can be very different. There are 4 different types of nozzles: recessed, flush, protruding or adjustable.
What can occur if a gun liner is dirty or damaged?
A worn out or kinked liner, or build-up of debris, filings, dirt and other foreign material inside the welding liner, the wrong size liner and misalignments or gaps at the liner junctions caused by an improperly trimmed liner can all cause the wire to feed erratically.
How many psi is a full Argon tank?
120psi (on the main gauge that shows tank pressure) for Argon/CO2 mix should be about empty. Those are high pressure tanks, like an oxygen tank, and I’d expect to see at least 1500 psi on a full one. Straight CO2 are a lower pressure tank, normally they’re under 1000 psi when full.
Why do my MIG welds look so bad?
Wire feed speed/amperage too high – Setting the wire feed speed or amperage too high (depending on what type of machine you’re using) can cause poor arc starts and lead to an excessively wide weld bead, burn-through and distortion.
What are some of the things you should watch for when MIG welding?
Putting to practice any of these tips is likely to improve the quality and durability of your weld.
- Clean, Clean, Clean.
- Get a Great Ground.
- Keep Your Stickout Short.
- Use Both Hands.
- Listen To Your Welder.
- Keep The Arc Up Front.
- Match Drive Rolls, Gun Cable Liner, Contact Tip to the Wire Size.
- Push or Pull.
