Unique Features
The Thermal Arc 181i includes basic features to help beginners and home hobbyists enjoy their welding experiences.
Knob Control
With a simple knob control style, users can choose precise wire feed speeds depending on the wire and metal used in the project.
MIG Adaptor
Designed specifically for use with the Tweco MIG gun, this adapter allows customers to switch the welder to MIG capabilities.
Arc Force Adjustments
When using the welder in stick mode, customers can control the arc force used in any individual project. Arc force alternations change the amount of penetration through the metal.
Arc Control
When in MIG mode, the welder enables its arc control function. This function allows the user to change the intensity of the arc and reduce the risk of splatter.
Overload Protection
The Thermal Arc 181i shuts off the power source if the duty cycle is overloaded. The machine must then cool itself down using its built-in fan until it can be used again.
Performance & Ease of Transportation
Despite some performance flaws with the Thermal Arc 181i, many customers enjoy using it for light projects and learning.
This portable welding machine makes the most of its small size by incorporating plenty of features.
Performance
The Thermal Arc 181i welder performs well when used for mild steel. However, most customers recommend avoiding aluminum when welding with this product, which limits its range of materials.
Additionally, the Thermal Arc 181i causes more splatter than some other comparable welders. It requires more skill to use than other lightweight beginner-focused machines.
Despite its slight flaws, the product’s versatility in terms of welding style allows it to perform well enough for the majority of household and everyday consumers.
Ease of Transportation
At only 32 pounds, the Thermal Arc 181i offers one of the lightest overall weights of the portable welding machines on the market.
However, it does not include many add-ons, which often increase the weight of the welder.
Additionally, the Thermal Arc 181i doesn’t include a carrying bag, unlike many other models. Despite this, it remains useful for travel and for transporting around the home or workshop.
Weld Quality and Available Options
Customers usually report good results and solid weld quality from the Thermal Arc 181i welder.
Although it doesn’t hold up quite as long or offer as many settings and adjustments as other welders, it regularly produces smooth, clean welds.
It may take some time to get used to the three types of welding available in this machine. However, customers who put in the time and effort to practice are rewarded with excellent project results.
There are no additional options available with the Thermal Arc 181i. It does, however, include some add-on accessories:
- Tweco TIG Torch Package: This product comes from the same parent company and works specifically with the Thermal Arc 181i welder.
- Foot Control Pedal: Available from a few manufacturers, the welder functions with an optional foot pedal for precision control.
Ease of Maintenance, Repairs & Warranty
Customers may have some difficulty getting in touch with Thermal Arc for issues related to repairs and replacements.
Since Thermal Arc itself does not exist as a company anymore, customers must contact the parent company ESAB instead.
Some parts required for repairing the Thermal Arc 181i welder exist only as secondhand items and are no longer produced by the company.
Therefore, most customers contact licensed technicians to repair their welders.
Maintenance requirements for this welder involve crucial upkeep that customers should perform regularly.
Cables should be checked every three months and replaced when necessary. Doors and hinges should also be replaced as soon as they no longer function.
Clean the welder at least every six months, or more often for more frequent use. Change any tips and spools used when they wear out.
