Jasic EPA-140 EVO Power Arc 140

Jasic EPA-140 EVO Power Arc 140   

he Jasic EVO Power ARC 140 offers professional grade performance and solid build quality at an affordable price, making it perfect for site maintenance teams and hobbyists. Its advanced inverter technology and MMA parameter control are combined with a compact, ergonomic design and straightforward operation, ensuring reliable and precise welding every time.

The EVO series from Jasic replaces the hugely popular, tried and tested PRO range, which has been around for 10 years. The EVO still has the great Jasic build quality, with a number of tweaks that are focused on usability and improved performance. Featuring intelligent Synergic control as standard, the Jasic EVO 140 ensures simple setup and outstanding ease of use. Built with Jasic’s renowned quality and reliability, the EVO power Arc offers exceptional weld performance, warranty coverage, and trusted after sales support. This Jasic inverter is compact and lightweight machine weighing just 5.5kg, making it perfect for on site maintenance tasks.

Features

• Intelligent synergic control –  Simplifies setup and delivers consistent, precise welds.
• Smart Lift TIG – Allows smooth TIG starts with minimal spatter for cleaner welds.
• Anti-stick, adjustable hot start and arc force – Reduce electrode sticking and improve arc stability.
• ABAP (Active Balancing Air Passage) – Provides efficient cooling, extending machine lifespan.
• On demand Fan – Lowers energy use and reduces dust intake, protecting internal components.
• Voltage Reduction Device (VRD) –  enhances operator safety in hazardous environments.
• Key power electronic component protection –  safeguards the machine against damage.
• Overcurrent and overheat protection –  prevent downtime and extend machine reliability.
• 35-50mm cable sockets –  Allows easy connection to a range of welding cables.
• AVR Generator Friendly – Compatible with unstable power sources for on-site flexibility.

As a result of extensive research and development the EVO Power Arc 140 (EPA-140) Inverter Welder boasts a wide range of new features. Firstly, Intelligent Synergic Control allows for pre-programmed setting of electrode sizes for easy operation and setup.  The unit includes a selection ability for electrode sizes.

Smart Lift TIG controls the short circuit current at the start consequently avoiding tungsten contamination.  Furthermore, the system also identifies accidental short circuits to maintain welding.  In addition, the arc length cut off feature eliminates arc wander.

A sleep function to save power kicks in when not the machine has not been in use to reduce energy consumption.  A simple push of a button awakens the machine, ready for the next weld.  A fan on demand maintains optimum working temperature by starting when required but stops when it is not required, again to decrease energy consumption and noise emissions.

With safety and efficiency in mind, the Jasic EVO Power Arc 140 is fitted with a voltage reduction device (VRD) and works by lowering the open circuit voltage (OCV) to a safer level.  Therefore, reducing any potential dangers, since open circuit voltage is produced when a welding machine is switched on and could normally be hazardous by accidentally touching the welding holder or electrode.

Overcurrent and overheat protection is also inbuilt to ensure the machine does not cause damage to itself.

In a word-The EVO ARC has a very straightforward front panel.

From left to right, you will first encounter a green button that allows you to switch between MMA mode and Smart Lift TIG mode.

The second button allows you to toggle between electrode sizes of 2.5mm, 3.2mm, and 4.0mm, in addition there is also a setting that gives the option for a manual custom input.

The third button allows you to switch between amperage control, hot start and arc force.

The potentiometer controlled dial provides a smooth and accurate means of setting your required amperage.

Finally, the last button you will notice (4th from the left) lets you switch between the machine controls or a separate wired/wireless remote control, which is available as an additional accessory.

Synergic set up-The front panel allows the user to select the electrode diameter being used.  The machine will then default to a set amperage which is deemed appropriate for the welding rod size.  The knob can be used to increase or decrease the amperage within a set range for the electrode size selected.

Rather not use this?  No problem – select the dotted parameter and the machine can be used fully manually.
