Wielding an arc welder can be tricky if you don’t know what you’re doing. That’s why it is important to learn the basics of welding thin metal before jumping right in. This article will show you how to weld thin metal with arc welder, as well as 7 tips for beginners!
How to Weld Thin Metal with Arc Welder
Tip 1: Prepare the Metal
A good place to start is with a metal that has already been prepared for welding. If you are using raw steel, it will need to be ground and sanded down so there is no rust or dirt on its surface. You can also use small pieces of tin as filler metals if they have holes punched in them for easier melting and joining, this might happen when thin metal sheets get soldered together by another welder at their factory before arriving at your workshop/studio.
Tip 2: Use Protective Gear!
Wear plenty of protective gear while working with an arc welder because the air around us becomes electrically charged during operation, making breathing hazardous (not to mention dangerous).
Make sure you wear leather gloves to protect your hands, steel toe-cap boots for safety, and a welding helmet that is rated according to the thickness of the metal you are working with.
Tip 3: Make Sure You have Good Ventilation
Ensure there’s plenty of fresh air in the space where you will be doing your work because arc welders give off fumes when used, which can damage both lungs and brain tissue if inhaled or absorbed through skin contact. For this reason – always ensure good ventilation while welding thin metal!
Tip 4: Consider Your Joints & Layout
When it comes time to join pieces together during fabrication after cutting out shapes from raw material using an angle grinder, consider how best to fit them together. You can butt weld pieces up against each other, overlap them slightly, or use filler rods to fill in gaps between sheets of metal if they’re too thin to be joined directly with the arc welder itself.
Tip 5: Use Filler Rods When Necessary
Filler rods are made from metals like steel and zinc alloys which work well for joining two pieces together at their interface (the point where one piece ends and another begins).
For this reason – using a rod that matches your base material is important because it will produce stronger joints than those created by welding alone without any kind of filler inserted into the joint first. Be careful not to leave unsightly gaps on either side when you’re done welding, though!
Tip 6: Weld in Several Increments
If you find unsightly gaps between pieces of metal that need to be welded together, consider using a technique called ‘stitch’ or ‘skip’ welding, which involves moving the arc welder along either side while still maintaining contact with both.
For example – if you were joining two sheets of steel by their edges and only wanted to leave an eighth-inch gap on each edge before filling it in again with another pass over your joint, try setting your machine’s amperage at around fifteen amps and starting halfway down one sheet so the tip is just touching its surface when turned on. Then work up from this position, welding each quarter-inch increment until you reach the opposite edge.
Tip 7: Clean Your Arc Welder’s Tip
The tip of your arc welder is where all the action happens, so it makes sense to keep this part clean and free from debris or contaminants like paint, oil, rust, etc. because these things can cause poor quality welds which are often weak at best and prone to breaking under pressure once they’ve cooled down again later on after fabrication has finished during production processes using metal cutters.
A wire brush should do just fine for cleaning an electric welding machine with a tungsten electrode attached. If you’re having trouble getting rid of stubborn dirt, try disassembling its parts completely before scrubbing away.
Welding thin metals is a little more complicated than welding thick ones because of the way their surface area affects how they conduct heat during operation – but these tips provide a foolproof guide to ensuring that you get it right for your next project or production line!
