Who it is for: If you want maximum amperage and a complete feature set under $1,000, the TIG225X delivers. The included CK torch and solid pedal mean you spend less on upgrades right away.

AC vs DC TIG — Which Do You Need?

This is the single most important decision when buying a TIG welder for your home shop.

DC TIG handles steel, stainless steel, chromoly, copper, and titanium. The current flows in one direction, producing a focused, deep-penetrating arc. If you only plan to weld steel and stainless, a DC-only machine will save you money.

AC TIG is required for aluminum and magnesium. Alternating current provides a cleaning action that breaks through the oxide layer on aluminum — without it, you cannot get a proper fusion weld. AC/DC machines do everything a DC machine does, plus aluminum.

Our recommendation: Buy AC/DC. Even if aluminum is not in your plans today, it almost certainly will be. Every welder on our list above includes both AC and DC, and the price difference between AC/DC and DC-only machines has shrunk to under $200 in most cases.

Key Features to Consider

Amperage and Duty Cycle

For home shop work, 200A handles the vast majority of tasks. You can TIG weld material from paper-thin sheet metal up to 3/8” steel plate at 200A. Duty cycle matters more than peak amperage — a machine with 60% duty cycle at 150A is more useful than one with 100% at 50A.

Pulse Settings

Pulse TIG alternates between a high (peak) current and a low (background) current at a set frequency. This reduces heat input, minimizes warping on thin material, and produces those distinctive stacked-dime bead patterns. For home shop work, pulse frequencies between 1-10 Hz are most useful for visible bead control, while higher frequencies (50-250 Hz) help with heat management.

Foot Pedal vs Torch Control

A foot pedal gives you real-time amperage control while welding — press harder for more heat, ease off for less. This is the standard and preferred method for table work. Torch-mounted controls (2T/4T switches) are necessary for out-of-position welding where a pedal is impractical. The best home-shop TIG welders include both options.

HF vs Lift-Arc Start

High-frequency (HF) start initiates the arc without touching the tungsten to the workpiece, eliminating contamination. Lift-arc start requires you to touch down and lift off, which is simpler but can contaminate the tungsten. HF start is strongly preferred for TIG welding. Be aware that HF start can interfere with nearby electronics — keep computers and CNC controllers away from the welding area.

Budgeting for a TIG Setup

The welder itself is only part of the total cost. Here is what a complete home TIG setup runs:

Total estimated cost: $900-2,400 depending on welder choice and whether you buy upgrades immediately or over time.

FAQ

Is TIG welding too hard for a beginner?

TIG welding has a steeper learning curve than MIG, but it is absolutely learnable at home. Most people can lay basic beads within a few hours of practice. Mastering aluminum TIG takes longer — expect weeks of regular practice before producing clean aluminum welds. Starting on steel with DC TIG is the easiest path.

Can I TIG weld on 110V household power?

Yes. Every welder on this list supports 110V input. However, you will be limited to roughly 130-150A on 110V, which caps your material thickness at about 3/16” steel. For full 200A+ capability, you need a 220V outlet — which any electrician can install for $200-400.

What gas do I need for TIG welding?

Pure argon (100%) is the standard shielding gas for TIG welding on all common metals — steel, stainless, aluminum, and chromoly. Unlike MIG welding, TIG does not use mixed gases in most applications. An 80 cubic foot tank costs $100-150 to purchase and $30-50 per refill, lasting roughly 10-15 hours of welding.

How does TIG compare to MIG for a home shop?

MIG is faster, easier to learn, and better for thicker structural work. TIG is slower but produces cleaner, more precise welds with no spatter. Most serious home welders eventually own both. If you can only buy one, MIG is more versatile for general fabrication. Read our full MIG vs TIG vs Stick comparison for a detailed breakdown.

Do I need a water-cooled torch for home TIG welding?

For most home shop work, no. Air-cooled torches handle amperage up to 200A for reasonable duty cycles. Water-cooled torches become necessary when welding at high amperage for extended periods — typically above 200A at duty cycles over 60%. They add $300-600 to your setup cost for a cooler and torch assembly.

What size tungsten should I use?

For a home shop, 3/32” diameter 2% lanthanated (blue band) tungsten covers most work on both AC and DC. Use 1/16” for thin material under 1/8”, and 1/8” for heavier work above 150A. Lanthanated tungsten has replaced thoriated (red) as the standard because it performs equally well without the low-level radioactivity concerns.
