Features

Portable

In the shop or at the jobsite—at 6.0 kg (13.2 lb.) the shoulder strap allows the end user to easily move from location to location.

Simple-to-use operator interface

Inverter-based, DC power source has a simple-to-use operator interface providing only the necessary controls in a compact machine.

Dual fan technology

An optimised power source cooling system which enables the machine to operate at a lower temperature, thus increasing its performance and life cycle.

Thermal overload protection with indicator light

Helps prevent machine damage if the duty cycle is exceeded or airflow is blocked.

VRD function

Is a simple design that reduces the open-circuit voltage to 20 volts when the welding power source is not in use.

Digital meter with presetting

Shows preset current before welding and actual value during welding.

Full-function remote control connector

For precise amperage control for critical welds on thin materials.

Selectable trigger configuration

Allows the operator to choose standard or 2T trigger method.

Built-in gas solenoid

Eliminates the need for a bulky torch with gas valve.

Built-in upslope/downslope function

Helps provide better arc starts and reduces craters.

Adjustable preflow and postflow

Gives operator better control of the gas parameters affecting weld zone.

Lift-Arc™

Start provides TIG arc starting without the use of high frequency or the risk of tungsten contamination.

HF start

For non-contact TIG arc starting that eliminates tungsten or material contamination.

Built-in pulsing capabilities

Allow the operator to select from four fixed pulse frequencies to satisfy the application.

Best-in-class stick and TIG arc characteristics

For those demanding jobs.

Adjustable Hot Start™

For stick arc starts. Adjust the optimal start current for the application. The current auto matically increases the output amperage at the start of a weld.

Adjustable Arc Force™

Prevents sticking. Adjust the optimal arc force value. Adjustable arc force supports positional welding by increasing the output amperage.
