You keep burning holes when welding primarily due to too much heat in one spot for too long, often from high amperage/voltage, slow travel speed, or poor fit-up, especially on thin metal; other culprits include contamination or insufficient heat sinking. To fix it, lower your heat settings (amperage/voltage), speed up your movement, ensure clean metal, use tack welds for stability, or try a copper backing bar to draw heat away.
Make sure your tip of your welder is cleaned out if MIG welding. From the looks of it it's a MIG weld. The holes re called porosity. It could mean your nozzle is clogged. You're out of gas and some other things like too far from your weld. That's all the tips I can give you.
How to Weld Thin Metal Without Burning Through (Step-by-Step)
These golden rules are as follows: Joint preparation is important. Welding machine set-up is the vital thing to some smooth weld. Comfort is a bit more important than welding technique.
Yes, you absolutely can make $100,000 a year welding, but it usually requires specialization, advanced skills, experience, and often travel or hazardous conditions, with roles like pipeline or underwater welding offering the highest potential, though even general welders can reach this with hustle, owning equipment, and working in high-demand areas. Entry-level pay is lower, but significant growth is possible, with top earners exceeding six figures through dedication and strategic career moves.
TIG welding is the hardest form of welding to learn for a variety of reasons. The process of TIG welding is slow and takes time to get used to as a beginner. A TIG welder requires a foot pedal to feed the electrode and control the variable amperage while maintaining a steady hand at the welding torch.
Touching hot equipment such as electrode holders, gun tips, and nozzles can cause burns. Always wear dry, insulating gloves. Allow a cooling period before touching these and other parts of equipment that are near the actual welding or cutting operation.
Do potatoes help welders flash? Using raw potatoes for welder's flash is a folk remedy without scientific backing. While the coolness of a potato slice may provide temporary relief, it doesn't treat the underlying UV damage to the cornea.
Isaiah 41:7 Amplified Bible (AMP)
So the craftsman encourages the goldsmith, And he who smooths metal with the smith's hammer encourages him who beats the anvil, Saying of the soldering (welding), “That is good”; And he fastens the idol with nails, So that it will not totter nor be moved.
The 5 Highest-Paying Welding Jobs
If you're too hot, you'll get a lot of batter beside the weld, and it'll be really pointy. In the center of the weld, there'll be, like, little arrows that are really sharp, really pointy. And if you're too cold, and the weld will kind of glob up.
Your argon regulator should typically be set between 15 to 25 cubic feet per hour (CFH) for most MIG and TIG welding applications. The exact setting depends on factors like nozzle size, welding environment, and material thickness. Always check your equipment manual for the recommended flow rate for your specific setup.
Exposure to harmful fumes and gases
Even in open spaces, over time, exposure to carcinogens like hexavalent chromium, cadmium, beryllium, nickel, arsenic, and substances causing neurological damage, such as manganese, can shorten a welder's life.
The phenomenon of blowing holes occurs when undesired holes form in the welded area, compromising the integrity of the joint. Its caused by the weld pool becoming too hot and gravity pulling the the liquid. It is mainly found in thinner materials and not just in steel.
The use of AC current markedly reduces arc blow. The rapid reversal of the current induces eddy currents in the base metal, and the fields set up by the eddy currents greatly reduce the strength of the magnetic fields that cause arc blow.

About flash burns
That's why it's sometimes called 'welder's flash' or 'arc eye'. Flash burns are like sunburn in the eye and can affect both your eyes. Your cornea can repair itself in one to two days, and usually heals without leaving a scar. However, if the flash burn is not treated, an infection may start.
While both welding fumes and cigarette smoke are undeniably harmful, the extent of their impact varies based on exposure, duration, and specific substances involved. Welding fumes are particularly associated with an increased risk of lung cancer.
The best way to keep an arc consistent (and lit) is by holding your electrode a steady distance from the plate. In general, holding it roughly 3mm off the workpiece will give a good arc. If your arc gets too short, then you're going to lower your voltage and stick your electrode to the workpiece.
To avoid secondary voltage shock, welding operators should wear dry gloves in good condition, never touch the electrode or metal parts of the electrode holder with skin or wet clothing and be sure to insulate themselves from the work and ground, keeping dry insulation between their body and the metal being welded or ...
MIG (metal inert gas) welding is an excellent choice for beginning welders. This easy-to-handle machine is usually spool-fed to create professional-looking joints on both thick and thin metals. MIG welding requires separate shielding gas but doesn't require chipping and cleaning slag as the stick welding process can.
A 6G welder qualification is a certification that shows a welder can successfully perform welding in the 6G position. This certification is highly valued because it proves a welder can handle the most complex welding tasks. The qualification process usually involves: Welding a test pipe fixed at a 45-degree angle.
TIG welded joins are typically stronger than those produced by MIG welding. This is because the narrow, focused arc created by TIG welders offers better penetration of the metal. In addition, the TIG weld beads, when applied correctly, contain few holes and other defects that can weaken the weld.
