Just learning to weld, I have a hard time getting the weld started. Any tips?

all you need to know to weld like an expert.

Wire feed welding machines are also known as mig welding machines or for short, a mig welder.

Regardless of what you call the machine they all have the same basic features.

Going by the description of the name, you need to feed wire.  As this wire is feeding, electricity melts it and the base metal together.  This is essentially how it works.  As long as you keep wire up to the electric arc you will be able to weld all day long.

Now to control this you hold on to what is called a mig welding gun.  This allows you to accurately place where you want your weld to be.

Wire feed welding machines are rated by their power output in amperage (Amps).  So for example a small machine might only be rated at say 90 amps and a large machine might be rated at 500 amps.

The more amps the more electricity is used which means you have to heat needed to weld thick metal.

Another point to look at, is what is called duty cycle.  Now just because one machine might be rated at 100 amps and another machine is rated at 140 amps this doesn’t mean that the 140 amp machine is better.  Welding duty cycle is a figure that is given for how much work the welder can do at full power and for how long.

This is rated in a percentage, so for example 20%, 30% and 40%.  What this tells you is that how long you can weld for in either a five minute block or ten minute block of time.  So if your machine is rated at 20% duty cycle you could only weld at full power for 20% of either 5 minutes or 10 minutes. The trick here is to know what time frame your duty cycle is rated at.

So let’s assume that your machine is using a 10 minute time cycle.  This means that you can weld for two minutes at full power (20%).  Now for the rest of the time which is eight minutes you cannot weld at all, you have to let the machine cool down.  This is definitely one thing to look out for when you go to buy a mig welding machine.

A wire feed welding machine will also use consumables.  The main consumables that you will need to keep buying will be your contact tips, nozzles and shrouds and gas diffuser.  There are other consumables that do need replacing but not so frequently.  They are your liner, contact tip holder and maybe a few O-rings depending on what model welding torch you use.

To find out more detailed information about wire feed welding machines go to my website and see some photos and videos all about welding:  Wire Feed Welding Machines

Mig welding is just another name for Wire feeder welding. The fundamental idea behind wire feed welding is that you use a welding wire that constantly feeds through a MIG welding gun when you grip the trigger.

This is a nonstop welding process. You keep your finger on the trigger and the base metal, welding wire touching you can do wire feed weld all day. There are many different types of welding wire. You can use for many different welding applications.

Welding wire is the most commonly used for more than likely an AWS ER70S-6 classification wire. This welding wire is used fabrication shops and all welding for many different types of welds.

A cover wound wind of wire will be evenly wound onto the spool from left to right with each and every layer of wire in order to sitting next to the other. This type of process a lot better for wire feedability as there will be no bends and little kinks in the wire feed.

Random wound will be exactly random wound wire in any old type of fashioned.Because the wire is wound on the spool with each and every layer in a random fashion, the wire will cross over itself a a small amount of times. The spool starts to fill up with the wire feed, each and every time there is a intersect of the wires it can make a little bend in the wire.

These little bends in the wire can damage your wire feedability which in turn will affect your overall weld quality and feed.

When you are using a MIG welding machine or a wire feed welding machine you have welding consumables that need replacing on a regular basis. Every MIG welding machine gun will have a shroud and contact tip or a nozzle. And then depending on which type of brand welding torch you have there will also be a gas diffuser or some kind of insulator.

I guess that most home welders or DIY will use what is meant by gasless welding wire. This process is also known as a flux cored wire. Be careful though because there are two different types of flux cored welding wires. There are a lot more than two, but for general home welding wire feed make sure that you get a gasless MIG welding wire feed that is an E71T-GS.

Now if you want to do decide to use a gasless MIG welding wire you are going to have to modify the wire feed rolls. The reason for this mig welding wire is because it is a flux cored wire the wire is not solid all that way through. The flux is on the in the interior of the wire the wire is very soft.

So if the wire diameter is for dispute sake 0.9 mm you need to use a 1.0 mm get in touch with tip. This will really help with the smooth feeding of the wire and allow better welding.

Finally you’re going to have to use a a little larger get in touch with tip for when you use a flux cored wire.

I have a lincoln welder (flux core 100 weld pack hd) and i bought hobart wire for it, .035, just like my welder takes, is that going to be a problem at all?

Why has my MIG wire gone bad all of a sudden?

“I’ve been using this MIG wire for the last six months without a problem”. “Now after having used many spools the wire its gone bad”. “What’s happened?

Sound familiar? The trouble here is that the person or company that you bought your MIG wire from cannot guarantee you quality.

Did you buy the cheapest stuff you could find? Ha-ha…As the saying goes, “he who buys on price, and price only, gets what he paid for”.

Sounds harsh but that’s the truth. Quite often you find end users happily welding away with their current brand of MIG wire. When all of a sudden they go and open up the next new pallet of wire that just arrived, slap it on the machine and the welds are all over the place.

Spatter, burn backs wire not feeding properly and so. What’s going on, they think to themselves. “Ahh, I know, it must be a worn contact tip”. So off they go and replace the contact tip with a new one. But no, sure enough same problem. “Well, it’s been a while since I change the liner”. So off they go and do that. Yet sure enough the same problem is still there.

They think to themselves, “well I’ve changes everything else, it can’t be the wire. It’s brand new and I’ve been using it for over six months without any trouble”.

This is such a common thing to come across in the welding industry, and it affects everyone throughout the world. Whether you’re in the USA, Australia, New Zealand…anywhere.

So what is it, what’s the problem?

The problem is quality.

The person who is supplying your wire can not guarantee you quality. But you think to yourself, it can’t be the wire, no way. I’ve been using this (xxxx) brand wire for ages. They are a huge massive company, they sell MIG’s, TIG’s all sorts of welding gear no way can it be the wire that’s giving me problems….can it?

The trouble is that unless you are guaranteed the quality of you welding wire your “up a creek without a paddle”, so to speak.

With so many people selling welding wire these days it is extremely hard to come by a quality wire. The majority of goods made in the world today come from China or India. With huge populations and low wages, they are the cheapest places to buy things from.

There are over three hundred manufacturers of welding wire in China alone. What does this mean to the quality of your MIG wire?

This means that if the brand of wire on the box is (xxxx) they are not the manufacture of it. You need to ask the sales person….ARE YOU THE MANUFACTURER OF THIS WIRE?

Because what happens behind the scenes is the company you bought the wire from has a big argument with their supplier in China or where ever. And they say stuff ya….well go next door and buy from them. Hey with over 300 manufacturers in China alone they can pick and choose who they like.

So they change their manufacturing supplier, and this happens all the time. But when they change manufacturer the quality also changes. That’s why your wire has gone bad. And that’s why they can’t guarantee you the quality.

Simple as that.

Each time they change their manufacturing supplier the quality changes as well. There is a huge difference in quality of wires.

Okay so what do I do now, which wire do I buy?

The secret is to buy a wire that is supported by the manufacturer. You need a manufacturer that has been producing quality welding wires for years and years so that they have the art perfected.

Did you know that there are general “quality” MIG wires and precision MIG wires? Which type of wire do you think that the big boys use? When I say that I mean vehicle manufacturers, earthmoving manufacturers and so on, company’s that use it by the tonne. What do you think they are after in a welding wire?

They are after:

• Precision

• Reliability

• Repeatability

• Consistency

• Quality

• Accuracy

How much money would Toyota or Mitsubishi or Caterpillar lose per minute if a welding machine was down? I sure bet it would be an awful, awful lot of money. These manufactures don’t want a single welding machine in an assembly line to break down. Cause if one thing stops, the whole show stops.
