HOW TO DISTINGUISH THE DIFFERENT PROSPOT WELDERS

ProSpot is a world-renowned brand that specializes in welding equipment, including auto body repair. Thanks to their complete and diversified inventory, the Californian company offers several specialized equipment for different needs and different budgets.

In this article that we will help you distinguish the different most popular ProSpot welders, so that you can make an informed choice.

Resistance spot welders allow materials to be welded quickly and securely while meeting automotive manufacturers’ OEM standards. This welding process replicates the same method used in factories, delivering strength and weld quality equivalent to original factory welds.

*NEW*

I5S : smart Spot Welder 208-240V with Ergo Lift Assist™

The new Pro Spot i5S intelligent resistance spot welding system, a professional welder designed for automotive body shops, is equipped with the industry’s most advanced adaptive automatic welding technology.

The i5S automatically analyzes and adjusts welding energy in real time based on material composition, thickness, and resistance properties, including high-strength steels (HSS, AHSS, UHSS), ensuring OEM-compliant welds for body repair applications.

I4S : smart spot welder

The Pro Spot i4S is an intelligent resistance spot welder designed for automotive body shops, incorporating the trusted features of the i4 while adding advanced functionality. Fully automatic, it requires no manual adjustments, reducing the risk of errors and improving repair consistency.Its software automatically identifies the metal type and adjusts welding power and time, including for high-strength steels (HSS, AHSS, UHSS), ensuring OEM-compliant welds.
Built-in video training allows technicians to quickly access proper procedures, while Wi-Fi connectivity enables automatic software updates and easy email delivery of welding reports.

Equipped with the patented C2X arm, the i4S supports automatic welding in C-X mode without switching to manual mode, improving productivity and ease of use in the shop.

The i4S delivers advanced automotive welding technology designed to meet the demands of modern repairs.
A high-performance solution built to meet today’s and tomorrow’s needs!

PR-2000-HP : inverter Resistance Spot Welder

The PR-2000-HP is a resistance spot welder designed for automotive body shops, delivering performance comparable to the Pro Spot i4. It provides reliable and consistent welds for body repair applications.
Featuring an air-cooled system, it offers a robust, high-performance, and cost-effective solution ideal for welding steel panels and structural components, including certain high-strength steels, while meeting industry quality standards.

PHS-101-HP : hybrid battery operated spot welder

Is three-phase power unavailable in your body shop?
The PHS-101-HP resistance spot welder is the solution you need. This hybrid, battery-powered spot welder is designed to deliver powerful, OEM-compliant welds without requiring three-phase power.
Operating on four slow-charging batteries, it provides continuous high-amperage welding current, making it ideal for demanding body repair applications.

MIG : Metal Inert Gaz. Neutral gas that does not react with the molten metal

The MIG welders listed below are equipped with an intelligent synergic system that automatically adjusts shielding gas, welding parameters, and the synergic curve as soon as the technician pulls the trigger.

This automated operation simplifies MIG welding in automotive body repair, reduces the risk of setup errors, and ensures consistent, OEM-compliant welds, even when welding high-strength steels and modern materials used in automotive repair.
Three-phase power supplies can be configured in Delta (3-wire) or Wye (4-wire, including a neutral wire). Single-phase power supplies also use a neutral wire. It is important to verify your shop’s electrical configuration before selecting welding equipment.

SP-2 : smart MIG pulse welder

The SP-2 is a MIG welder designed for automotive body shops, ideal for welding steel, silicon bronze, and aluminum in body repair applications.
In synergic mode, the machine automatically adjusts its settings to deliver stable, high-quality welds that meet OEM standards. Welding can be performed in either continuous or pulsed mode, depending on the type of body repair being carried out.

SP-5 DP : single phase double pulse

The SP-5 DP is a MIG welder designed for automotive body and collision repair. It supports aluminum MIG welding, MIG brazing, and automotive steel welding. Thanks to its double-pulse technology, it delivers excellent heat control and superior weld finish, making it especially effective for vertical aluminum welding.

The SP-5 DP can store and recall more than 200 welding programs in a customizable job list, ensuring high consistency in repairs. Software updates are easily performed via USB to keep the equipment aligned with recommended repair methods.

SP5.3 : 3 phase smart double pulse MIG welder

The SP-5.3 is a three-phase MIG welder designed for body shops and meeting the requirements of certain OEM certifications. Thanks to its microprocessor controls, it delivers excellent performance on various materials and thicknesses, even during extended work cycles.

The machine also allows you to store and recall over 200 settings, ensuring optimal consistency in repairs. Software updates are easily performed via USB drive.
