Portable DC welders

The Thermal Arc Portable DC Welder Series offers from 95 Amps to 200 Amps of welding power, suitable for several industries and applications.


Thermal Arc has introduced the Thermal Arc Portable DC Welder Series. The series, which includes the 95S, 161S, 161STL, and 201TS, offers from 95 Amps to 200 Amps of welding power, and is suitable for several industries and applications, including:

  • Home hobbyists
  • Farm and ranch
  • Educational institutions
  • Maintenance and repair
  • Light industrial
  • Stainless steel & sanitary pipe fabrication
  • Petro / chemical fabrication
  • Shipboard installation and repair
  • On-Site & portable welding application

Thermal Arc is offering units with advanced operating features, more welding output power, and multi-Voltage input power with the capability of hooking up to either 115 or 230-Volt single phase power outlets.

The Thermal Arc 95S Portable DC Welder is designed for beginners, do-it-yourselfers or home hobbyists, and makes it easy and affordable to produce high quality welds at home, in the garage, or in the field. As the only product in its class with Stick and Lift TIG capabilities, the 95S is capable of delivering 95 Amps of power on standard 115-Volt circuits, and allows you to cover a wide range of light maintenance and repair jobs as well as some light fabrication.  The unit is available in two packages: a Stick welding package, and a combination Stick/TIG welding package.  The inverter welding power source is extremely portable at only 10 lbs.

The Thermal Arc 161S Portable DC Welder is designed for basic DC Stick and Lift TIG welding operations, and provides a greater range of output for the advanced hobbyist or for light industrial projects. It is capable of delivering 110 Amps on standard 115-Volt circuits for Stick & TIG welding. When used on 230-Volt circuits, maximum output is 160 Amps for either welding process. This welder features optimized hot start and arc-force circuits built into the power supply, delivering premium arc starting and arc control while Stick welding. This feature can also prevent some welding electrodes from sticking. The 161S is available in two standard packages: a Stick welding package, and a combination Stick/TIG welding package.

The Thermal Arc 161STL Portable DC Welder is designed to provide increased control and superior arc performance for tackling more demanding DC Stick and Lift TIG welding jobs.  It’s capable of delivering 110 Amps on standard 115-Volt circuits for stick welding, and 160 Amps for TIG. When used on 230-Volt circuits maximum output is 160 Amps for either welding process.

The 161STL includes optimized hot start and user adjustable arc-force circuits, which deliver premium arc starting and arc control during Stick welding, and can also prevent some welding electrodes from sticking. For improved control when DC Lift TIG welding, the 161STL includes a trigger hold function (2T / 4T), down slope timers, a gas solenoid for flow through gas, and the ability to use torch switches or a foot control. The included TIG torch has an integrated Amperage control dial and on/off switch, which allows for the ultimate in welding control and simplicity.

The Thermal Arc 201TS Portable DC Welder is ideal for tradesmen or welders with more experience.  This heavy-duty unit is designed to provide increased control with superior arc performance for highly demanding DC Stick and TIG welding jobs.  Powerful yet compact, the 201TS can provide a maximum output of 200 Amps for either welding process when used on 230 circuits.

Annual Salary Survey

After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.

The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
