Things To Consider When Buying

When you are going to be welding sheet metal you are going to be working with thinner materials than if you were welding pipe or making most common repairs on heavy equipment. In order to weld the thinner materials, you are going to need to have a welding machine that is capable of TIG or MIG welding processes.

Consider the following things about the welding machines you are looking at and you should be able to choose one that does the processes you need for the materials you will be working with most frequently.

Welding Process Capabilities

The processes that the machine can perform will determine what materials you can weld with it.

MIG is gas metal arc welding and requires shielding gas to operate. This is the easiest to learn the welding process and it is recommended if you are welding thin materials like sheet metal. It can also be used to weld thicker metals so it is an all-around effective welding process.

You can even create welds on materials that are located above your head and it welds about four times faster than basic stick welding.

TIG welding is gas tungsten welding that utilizes a non-consumable tungsten electrode and shielding gas like Argon. This is the perfect welding process for thin materials because it gives less distortion and high-quality finishes. The weld beads are prettier and you have complete heat control using a foot pedal or a hand control depending on your personal preferences and abilities.

Stick welding is shielded metal arc welding and it is not recommended for thin materials that are less than an 18 gauge in thickness. These machines have to be used outdoors and they are the least expensive of all of the welding machines.

Choosing a duty cycle

If you are welding thin materials like sheet metal or aluminum you want an MIG or TIG welding machine that has a duty cycle rating of 20% OR 30%. You do not need a really high duty cycle rating if you are going to be working on the thinner materials.

Amperage concerns

Thinner materials like sheet metal do not require high amperages. So you can choose a welder that has the lower amperage if you are going to work with thinner materials.

When using an MIG welder on an 18 gauge material you only need a 70 amp to be able to do the weld in one single pass.

Frequently Asked Questions

What type of welder is used for sheet metal?

If you are going to be welding on thin material like sheet metal you need a TIG or MIG welding machine. The TIG is often preferred of the two processes because TIG leaves a cleaner weld and gives you slightly more heat control.

Can sheet metal be welded?

Sheet metal can be welded. It is thin metal and that means that you will need to use either a TIG or MIG capable machine when you start welding it, and you have to have great control over your heat and your puddle.

Can you stick weld sheet metal?

You can use a stick welder and do some spot welding on sheet metal but for the majority of welding jobs utilizing sheet metal, you will need a welding machine that either does TIG or MIG welding.

Final Note 

If you are looking for a welding machine that can do all of the welding processes then we suggest the 2020 Weldpro 200 Amp Inverter Multi-Process Welder. It is a dual powered machine that allows you to perform any welding process that you choose.

If you want a welding machine that weighs less than 60 pounds but will give you the ability to weld most things then we suggest the Lotos TIG200ACDC 200A AC/DC Aluminum TIG Welder. It is a great TIG process device that is easy to use and versatile.

Welding sheet metal is not difficult if you have the right tools for the job.
