Do you need a darker or lighter welding helmet for arc welding?
A darker helmet shade, compared to gas welding. A shade of 10 for 70 amps, it works up from there, or you could buy a auto-darkening hood which you can see out of, but when you strick the rod on the metal it darkens to the right shade for you to still see out of.
Your welding helmet is too dark to see the work when welding?
The helmet holds the lens. Lenses come in different shades (darkness). Use the correct shade. Most welding applications call for a shade #10. TIG weldors usually use a shade #9. Plasma applications can call for a shade #11.
What is a general formula for welding output current and voltage relationship for MMA welding machines?
V= 0.05 i + 10 for mmaw welding v= 0.05 i + 20 for tig welding
What lens shade for 024 wire mig welding?
Depends on multiple factors, amperage, the person and their eyesight, toleration to light. I would suggest you start at shade 10 and work downwards with shade 7 being as low as you go.
Explain seam welding and percussion welding?
Seam welding- resistance welding process involving the use of (normally) copper or copper alloy rollers to simultaneously pass high current (10^4 amps and usually in pulses) and apply pressure to bond a lap seam between two pieces of sheet metal. Percussion Welding- arc welding process involving the use of a capacitor bank to bond on the order of milliseconds. A high current electric arc is developed between the items to be joined, and the items are rapidly accelerated together.
Is a number five lens darker than a number ten lens?
No the higher the number the darker the lens. 4 or 5 for gas (oxy/acetylene) welding. 9 for small TIG work and 10 - 11 - 12 for stick welding.
What is the difference between gas welding goggles and arc welding goggles?
If by gas welding you mean-oxyacetylene welding. The difference is just that arc welding requires a darker shade of lens. When oxyfuel gas welding (OFW) usually a shade 5 lens is recommended. When arc welding, a minimum of shade 10 lens should be used (actually shade should be determined by amount of current used).
What determines the correct shade of lens to use for welding?
The amount/brightness of light given off by the process used. Shade #4 or 5 when cutting or welding using the Oxy-Fuel process is usually sufficient. Shade #9, 10, or 11 when stick, MIG, or TIG welding depending of the material being welded and Amperage used. Aluminum reflects more heat and light than most other metals so a darker shade may be called for. TIG welding produces less smoke letting more light escape the weld area, darker shade, possibly. A person whose eyes are sensitive to bright light would probably use a darker shade. I've used shades #9, 10, 11, and 12 when welding. The #12 lens when TIG welding on a ships' propeller using 300 to 400 Amps. Water cooled torch, 5/32" Tungsten. A lot of heat/light was reflected from the surface of the metal. Use as dark a shade that still allows you to see clearly. Remember, the higher the number the darker the shade.
