Let’s be honest, safety isn’t the “cool” part of welding. Most shops aren’t stopping mid-job to talk about air quality, and almost nobody’s bragging about their respirator setup (except maybe if you own one of these fancy Optrel PAPRs).
​
But welding fumes are one of those things where a little understanding goes a long way. They're an unavoidable part of the job and we’re not here to create fear but to give you the facts. Knowing what you’re working with helps you make smarter calls for yourself and the people around you.

They’re not just smoke! Welding fumes are a complex mix of metal oxides, gases, and vapors created when heat from the arc or flame melts base metals, filler metals, fluxes, and coatings.

Basically, when metal gets hot enough, it vaporizes. As it cools, it turns into tiny particles that hang in the air and these particles are small enough to get deep into your lungs. On top of that, you’ve got gases created by the arc, shielding gas interactions, and coatings burning off.

Different materials = different exposure. So what you end up breathing depends on what you’re welding, how you’re welding it, and what your setup looks like.

So let's talk about what's actually in these fumes, getting into the specifics on where the most common ones welders encounter come from and what they have they potential to cause. 

Skill and precision in MIG welding don’t magically appear when the arc is struck. It starts well before that with a full understanding of how MIG welding works and how your system is set up. Weld quality, joint integrity, and overall appearance are all directly tied to arc stability which is the result of experience, proper setup, and consistent execution!

While operator skill is always important, even the most experienced welder will struggle if the gun, consumables, wire, power source, etc., just aren’t working together. So let's go over the core parts of your MIG setup and gain a better understanding of how each element influences the arc, so you can produce consistent, high-quality welds you can be proud of.

Each one of the components below contributes to how the arc is generated, sustained, and controlled. The top four- Power Source, Gun, Consumables, and Filler Metal- don’t operate in isolation. A strong power source can’t compensate for poor consumables, and the right wire won’t do well if your gun or feeding system is struggling. In addition to these core building blocks, wire feeding and shielding gas selection play critical supporting roles in maintaining arc stability.

We know that getting started in your welding career can be costly, which is why we are always excited to share any and all financial aid or scholarship opportunities we come across that are geared towards students eager to forge a path in the skilled trades!

Today we're spotlighting a scholarship opportunity from Metal Supermarkets! They're committed to nurturing the next generation of skilled tradespeople through their trade school scholarship program and this year they've doubled their scholarship funds to $20,000, meaning that 8 lucky recipients will receive $2,500 that can be used for training from a trade school, like Earlbeck's Technical Center!

Securing the funds to get started on your welding career journey can be a challenge. At Earlbeck Technical Center we want you to succeed not struggle, so we do our best to keep costs low for our students and are committed to sharing any opportunity we come across to score funds that can be used for our welder training classes!

Focusing on apprenticeship programs and trade schools instead of university programs, the mikeroweWORKS Foundation aims to give hardworking individuals the leg up they need to advance in their career journey. Great news is that welder training through Earlbeck is an approved program for the mikeroweWORKS Work Ethic Scholarship! 

​This year they have expanded their application window, awarding scholarships four times a year, based on when your application is submitted. Giving you the chance to apply when you're ready and when funding matters most. 

These scholarship funds are for tuition, books, and/or tool costs for your course load, so awards can vary and they will ask for you to submit a tuition bill or cost statement from your school. Review the eligibility criteria and award timeline below for more information, or visit the mikeroweWORKS website.

In order to be eligible to apply you must:

• Be a U.S. citizen.
• ​Be a high school senior, high school graduate, or have a GED equivalent.
• Be enrolled or plan to enroll in an approved trade-related program at an accredited two-year college, vocational, or technical school, or other approved technical institute in the United States. 
• Be able to provide a current tuition bill or cost statement from your school.

Awards are given out four times a year, based on when you submit your application:

• June 2026 - Apply by April 30, 2026
• August 2026 - Apply by June 30, 2026
• October 2026 - Apply August 30, 2026
• December 2026 - Apply by October 31, 2026

NOTE: Former recipients may reapply for a second round of funding, granted they disclose that they were a previous recipient, provide a reason for applying, and still meet the above eligibility requirements.

This year, you can apply for a scholarship any time between February 23, 2026 until October 31, 2026. ​

​YOU'LL HAVE TO:

• • Enroll in an approved program
  • Sign the S.W.E.A.T. Pledge. ("Skill & Work Ethic Aren't Taboo")
  • Answer four short questions about the S.W.E.A.T. Pledge
  • Make a 45-60 second video
  • Submit two references from a teacher or boss
  • Verify your school cost with a tuition bill or cost statement
  • Provide high school or college transcript
  • Complete the application online​

Your application will be reviewed based on a rubric, taking into account your chosen program and school, the strength of your references, your video content, your short response answers, your financial need, and most importantly: your ability to demonstrate a solid work ethic.

They will also consider the completeness of your application, so be sure to double check everything before you submit!
