Do You Need a Multi-Process Welder?

Here are the top reasons why you could benefit from having a combo welder:

Types of Welding Machines

When buying a welding machine, you’ll find that they’re available in several types.

Here’s what you need to know about each of them:

Space Economy

Space is usually in short supply, whether you’re working in a workshop, onsite, or at home. You can organize your workspace better with fewer devices.

Having one machine instead of three frees up your room. As a general rule, open spaces are also safer and easier to move around.

Organization

If you’ve worked in any site, you’ll come to appreciate this feature. In short, well-organized places are easy on the eye and encourage productivity.

A combo creates less clutter around your workstation, and you wouldn’t need multiple sets of branded accessories, leads everywhere, in addition to several massive devices.

Effective Budgeting

A multi-process welder costs much less than three specialized welders. The standardized consumables and accessory sets also contribute to cost-economy.

Familiarity

We get the best results from the machines we know well. If you can use one device for three different welding purposes, it often reflects positively on the quality of your work.

How to Choose a Multi-Process Welder

These are the main points you should consider before buying a multi-process welding machine

Intended Usage

The type of material and thickness you usually work on are defining factors of the kind of welding combo you should choose.

If you often work with steel alloys and stainless steel, you can pretty much use any welding method.

You can use MIG or AC TIG for your aluminum pieces. There’s a constant debate as to which method is easier or more efficient, and it hasn’t been settled to my knowledge. My two pence on this is use MIG for precision work and AC TIG for quick high volume work.

You might be aware of the tricky business of welding cast iron, but you can try the Stick. If not for welding, it’s good for iron processing.

TIG is the sole proprietor of the ‘other’ metals like brass, chrome, and copper, in addition to the less abundant metals like titanium and magnesium.

MIG and TIG are good with thin sheet metals, while Stick and Flux Core handle thick objects nicely.

Skill Level & Preference

Welders are split in the middle as to which welding method is easier. It seems that the personal factor here is paramount.

This is understandable, as whatever you’re trained to do will always feel easier than any other process you’re not well-versed in.

When it comes to the new welders, everything is a clean slate. So, I’ll recommend MIG as an easier process. It’s easier to control, it has fewer variables to worry about, and beginners often gain more confidence as they cover ground with this simple method.

Speaking of confidence, I’ve seen many new technicians skip the TIG part whenever they could because ‘it was too complicated’. When these same guys tried it a few times, their beads eventually evened out. A few months later they swore that there’s nothing easier than TIG welding!

Veterans might lean towards MIG or TIG, and that’s understandable. Some seasoned welders like to broaden their repertoire or have work that requires a specific welding method.

This is another way the multi-process welding machine proves its capabilities. It offers a wide range of useful welding combinations and encourages welders to build new skills.

Weight & Portability

The weight of multi-process welders goes from 10 lbs to around 90 lbs. The compact units are great for site work, domestic repairs, farm work, and shipyard maintenance tasks.

The heavier machines often come with a host of features. It’s best to decide beforehand on the functions you need and whether you need to move your welder from spot to spot.
Location
The main bulk of your work could be outdoors onsite, or it could be mainly in the workshop. Decide where you work mostly, and that’ll point you to the right model.

MIG and TIG are generally good for workshops, where the airflow wouldn’t interfere with the gas shielding.

Stick and Flux Core are tolerant of outdoor work and will give good results even with dusty surroundings.

Duty Cycle

This tells you how long you can work with welder before it starts to overheat and calls for a recess.

The duty cycle is often expressed as a percentage, and we understand it as how much of a 10-minute interval the welder is on before it needs to cool itself off.

A 70% duty cycle means that you get 7 minutes of welding and 3 minutes of rest.

The industry norm hovers around 60%, and sometimes the nominal value is more than what you actually get, so aim for a higher value.

Budget

There’s a wide range of prices available for you to choose from. Price is often directly proportional to the quality, but we’ve seen some fine models at moderate prices.

There are hidden costs, and it’s essential to add them to your device budget for a more accurate estimate. Welding requires several accessories, and they tend to wear off quickly. You’ll also need to replenish your consumables regularly.

Safety gear is a one time purchase, so add it to the budget if this is your first welder, and you don’t own a set already. By all means don’t skimp on safety gear. So many injuries can be avoided by just putting on the right clothes.

I’ve seen many workers who didn’t take the safety procedures seriously enough, and there were always consequences.

How to Get the Best Results from Your Multi-Process Welder

Prepare your metal before welding. Polish the surface of sheet metals with a brush, and file a bevel tip along the borders to be welded for a tougher bond.

Brush the aluminum surface in one direction. If you go back and forth with a metal brush, the oxides will be ingrained into the metal.

Observe the proper direction of each welding technique. Should you drag and pull or advance and push? This depends on the welding method you’re using and the orientation of the piece you’re working on.

The speed of the wire advancement should correlate with the power you’re using. Any discrepancies leave a visible effect on your beads.

You should also regulate the pace of your filler with TIG welding to avoid a ‘hopping’ pattern on the welded piece.

Avoid directing the heat from the tungsten to the filler. And by all means, don’t dip the tungsten into the weld pool.

Follow the directional instructions on the electrodes before using the Stick. Mostly there’s a ‘1’ for ‘all positions’, but it’s best to double-check.

Try to set up your workstation in an ergonomic manner. Sitting comfortably helps in creating neat beads and welds that require minimal finishing touches.

This should keep welding defects to a minimum. I’ve seen a lot of messed-up beads, and these simple tips, take care of most of them.
