Question 4

What accessories come with the package?

Accepted Answer

The unit ships with a power cable set, a gas hose, an earth clamp, MMA and TIG torches, and a grounding cable, providing the essentials to get started right away.

Question 5

How does the inverter technology benefit my welding tasks?

Accepted Answer

The IGBT-based inverter, combined with a 25 kHz switching frequency and Power Factor Correction (PFC), delivers fast arc starts, smooth current control, energy efficiency, and reliable performance when welding aluminum and other non-ferrous materials.

Question 6

What materials and applications is this welder best suited for?

Accepted Answer

It's well-suited for welding steel, stainless steel, and aluminum (via TIG), making it a strong choice for fabrication, maintenance, automotive work, and general structural welding in challenging environments.

Question 7

How do I install and set up the Helvi Globus 270DC MMA Inverter Welder?

Accepted Answer

Place the unit on a stable surface, connect the power cable to a suitable power source, attach the earth clamp and welding torches (MMA and TIG), connect the gas line if TIG welding is used, power on, and use the TFT color touchscreen to configure your welding parameters before starting.

Question 8

How do I use TIG welding with lift-TIG and PWM on this machine?

Accepted Answer

For TIG welding, enable lift-TIG to lift the electrode off the work at the start for an easy arc initiation, then bring it into the weld pool. Use the PWM controls to modulate the output for stable heat and bead formation. Ensure proper shielding gas flow and select the appropriate tungsten and filler material for your metal.

Question 9

What is lift-TIG and why is it beneficial?

Accepted Answer

Lift-TIG reduces electrode sticking by lifting the tungsten slightly before initiating the arc, allowing a cleaner start and easier control, especially on positional TIG welds.

Question 10

How does the Helvi Globus 270DC compare to other similar models on Fepy?

Accepted Answer

Compared to related models, the Globus 270DC MMA Inverter Welder typically offers higher MMA current (270 A) with advanced digital pulse and AC frequency controls, along with lift-TIG capability and a color touchscreen for easier operation.
