Either too much amperage, travel speed too slow, or electrode too large for the metal thickness.

Why is welding in the downward position an advantage when welding on sheet metal?
Verticle down welding will always have lower penetration and less heat applied to the weld joint. As sheet metal is thinner and can not take excessive heat, verticle down reduces burn-through.
What is balance welding?
When welding on AC on a TIG welder you have to option to adjust how your arc passes from your torch to your metal and vice versa. This allows you to clawed your puddle clean of contaminants or burn your weld deeper while welding. When set on balanced, the arc equally passes in both directions.
What is the use of up hill welding and down hill welding?
Vertical up welding is preferred in most instances as better penetration is achieved and the slag does not run down into the arc. Down hand welding is mostly used on thin material so as not to burn thru the metal. Travel speed is usually increased also.
What is downhill welding?
MY question is (WHAT IS DOWNHILL WELDING) The correct term is Down Hand Welding. Most welds in the vertical position are made from bottom to top. Down Hand means welding from the top to bottom. These welds are usually made on thin metal as the heat input is lower, thereby reducing penetration/burn thru.
What are facts about welding?
# If you look into the flame you'll go blind, # if you touch the flame it will burn you, # your face is always hotter than your buttocks, # a cigarette always tastes better when lit by a torch flame, # always weld with a full gas tank, # you can get a tan/sunburn from welding, and # welding is fun when you weld random items together.

What are welding goggles?
Welding Goggles are goggles you wear when you are welding something to protect your eyes and around your eyes from sparks and tiny hot metal peices that can burn your eye. They are mainly for safety. Hope I helped@

Is welding pieces of metal is chemical change?
not it can always be changed back to its original shape. but if you burn metal which i dont consider doing it is a chemical change. like melting butter and burning butter. burning is chemical, melting can be cooled again into its original form.
How much are classes for welding?
Classes for welding are to help you learn how to weld and how not to burn yourself. They have books on how to weld and everything to do with it.
What happens when argon is burnt?
Argon won't burn. It is used in industrial processes like welding and metal smelting as a shielding gas. Some of those processes will heat the argon to 10,000 degrees Fahrenheit, and it doesn't burn. WRONG Henry Cavendish died when he heated Argon
What is the hazards of ozone burn on face through welding work?
While welding may cause a face burn if proper protective equipment is not used, that burn is caused by heat and light from the welding process, not from ozone. Where ozone is released in sufficient quantities, it may cause cough, headache, deep lung irritation and, in the more eggregious cases, pulmonary edema (fluid in the lungs)
What would you have to burn to reach 3000 degrees?
Simply burn the Acetylene (Ethyne) gas in open air. (As in case of gas welding).
What type of heat causes a burn?
The type of heat that causes a burn is gas!
Can welding cause cataracts?
Flash Burn and Blindness
