The HTP Invertig 221 Water Cooler Package adds a cooler, coolant, and torch to your existing machine. Here's exactly what's included and who should buy it.
Quick answer
The HTP Invertig 221 Water Cooler Package is an upgrade kit for owners who already have an Invertig 221 machine. It bundles a dual-voltage Arctic Chill cooler, two gallons of coolant, and your choice of 20 series TIG torch—but no welder.
Why the package excludes the machine
HTP sells this as an add-on because many Invertig 221 owners buy the air-cooled machine first and later decide to move to water cooling for longer TIG sessions or thinner aluminum work. Bundling the cooler, coolant, and torch together saves you from sourcing each part separately.
If you are starting from scratch, you will need to purchase the Invertig 221 welder separately. This package assumes you already own the machine.
Torch choices and what they mean for your setup
The package includes a 20 series TIG torch, and you select the length and neck type when ordering. A 20 series torch is smaller and more flexible than a standard air-cooled torch, which can help in tight joints. Because the cooler handles heat removal, you can use a more compact torch without overheating it as quickly.
Choose the torch length based on your typical work envelope—longer for large tables or out-of-position work, shorter for bench work where maneuverability matters. Neck type affects access to confined joints; a flex neck can be handy for odd angles, while a rigid neck offers more consistent control.
Invertig 221 water cooler package FAQ
- Does this package include a welding machine?
- No. The package is explicitly for upgrading an Invertig 221 you already own. If you need the welder, order it separately. Confirm you have the machine before ordering.
- What exactly is in the box?
- One dual voltage Arctic Chill Cooler, two gallons of coolant, and one 20 series TIG torch in your chosen length and neck type. No hoses, fittings, or machine are included beyond what is listed. Check that your existing torch connections match the included cooler and torch.
- Can I use this with a Single Voltage Invertig 221?
- Yes. The package is designed for both Single and Dual Voltage Invertig 221 machines. No need to upgrade your machine to add water cooling.
- Which torch length and neck should I pick?
- Pick a longer torch for reach on large work; a shorter one for control on bench work. Flex necks help in confined joints; rigid necks suit straight beads and consistent feeding. Match the torch to your most common joint access, not the rarest one.
- Do I need to buy coolant separately?
- No. Two gallons of coolant are included, which is enough to fill the cooler for initial use. Follow the cooler instructions for mixing and maintenance. You are ready to fill and run once the package arrives.
