How to choose the best aluminum tig welder for the money. 

  • The capacity of Aluminum Welding

Pure aluminum has a low strength. It also measures less weight, making it easy for welding or casting. This means aluminum is only used in low-temperature applications unless mixed with other elements. To join it, one can either braze or weld it. Therefore it’s combined with conventional methods applied to other metals. On the other hand, particular methods may be required. The strength needed, appearance, and alloy will determine the choice of technique.

  • Versatility

There are two methods used in Tig welding; Alternating current and Direct current. The DC modes work on all metals apart from aluminum. On the other hand, the AC suits both magnesium and aluminum. This means you must choose a welder capable of Alternating current. The AC set at high frequency gives consistency heat on the electrode. The DC models result in excess heat and low oxide cleaning.

  • Required Input Voltage

Where you intend to weld aluminum plays a crucial role in finding the best TIG welder. A voltage input of 220V can ideally supply enough power for a welder of 115v AC. This works best when welding indoors. The majority of TIG welding machines function correctly on this voltage input. Therefore the welder can either function on a single or three-phase plan.

  • Output Amperage

Always consider the output Amperage when choosing your ideal welding machine. A higher amperage means a broader range of materials to weld. When it comes to aluminum tig welder, one amp translates to 0.001 mm of material thickness. The more the output amperage, the more and thicker the materials to weld. A tig welder with a maximum of 200 amp works best for thin aluminum materials of 65mm.

  • Portability

How portable is the welder machine you intend to buy? A portable tig welder is more comfortable to carry from one point to the other. It should also be lightweight for a more comfortable movement when using it. You can go the extra mile and consider those welder with two carrying handles for great convenience.

  • IGBT Technology
Advancement in technology has seen a rise in powerful and efficient TIG welders.one of such latest innovations is the IGBT technology that allows for additional power and safety. This gives the welder a unique ability to produce both thin and thick materials. In addition, the technology gives the machine reliable, lasting arc stability. The Tig welder can work for many hours without any mechanical complications.

Can any tig welder weld aluminum? What rod do I use for aluminum tig welding?

Tig welding is far the best technique for welding. However, there are different types of TIG welders. While it’s true any tig welder can correctly work, there are several considerations likely to affect the quality of your final work. Some of such factors include the amperage and current. To weld aluminum, one can use the following rods;

4043

This is far the most suitable rod for AI-5Si weld metal deposits. It can be used with Ar shield gases for aluminum castings.

4047

This type of rod can be used with Ar shield gases as it contains AI-12Si deposits and 12% silicon. The rod also rarely cracks as it flows better.

5356

The 5356 rod contains Al-5Mg deposits can also be used with shield gases.

How to tig weld aluminum.

It takes both skills and practice to achieve high-quality welds. Below are four main steps used to tig weld aluminum.

Step 1: torch and hand positioning.

Hand placement is the first primary control in this game. Use the base of your hand and brace the welding torch firmly on your wrist all the way to your last finger. Now in a forward position, hold it against the table and keep it steady. Place the torch in a slight backward position while pulling the tungsten near to your work piece. Keeping the tungsten at a far distance from the work piece will cause much overheating. As a result, you are likely to lose puddle control.

Step 2: Movement coordination

Once you master torch control and hand placement, next is the flow and movement. Do it using gloves like typical welding. Firmly hold the torch with moderate pressure on the hands. Now in a smooth but motion, move your hands across the table. Move the whole hand, and not just fingers. This way, you quickly bring into line the hand movement and space of the tungsten. Next, push the torch forward to the filler metal. Ensure the filler rod is on the edge of the puddle for easy control. Use one hand to dab the filler metal, and the other remains steady. Do not deposit the filler metal while striking an arc.

Step 3Puddle control

Since aluminum absorbs heat fast, it’s essential to find the puddle and control it. Do not add the filler metal while doing this. Once the aluminum gets too hot, maintain the puddle width by slowly releasing the foot pedal. The reason for this is that too much heat tends to wash out the puddle fast. Easing on the foot pedal is the key to control the sinking heat. On the same line, less heat makes the arc erratic. Practice the art of maintaining speed by laying the puddle down without the filler.

Step 4: Adding the Filler Metal

Consistency is the key when introducing the filler metal. In a dab and move wave, slowly add the filler to the puddle. Avoid unnecessary torch movements when introducing as this creates the bead shape. Once you take control of the puddle, introduce the filler metal the margin. Create your rhythm at the same time you do it on the movement. Provided you keep a steady rhythm with consistent torch movement, the results will be impeccable. Keep doing this over and over again for perfect weld beads.

Conclusion

A good welder can meet all your welding needs. It not only makes the work more comfortable but also enjoyable. Picking the best aluminum tig welder for the money is a critical decision that requires commitment.
