STANDARD EQUIPMENT

  • Sherman MMA 220C welder

MMA 220C Sherman-workshop welding rectifier is an inverter device made in the IGBT technology, designed for manual welding with a coated electrode ( MMA method ) of structural and quality steel.

It also enables TIG welding with arc ignition by rubbing (after using an additional handle).

The welder is equipped with a welding current display , automatic ANTI STICK function to protect against damage to the device and adjustable HOT START functions to facilitate arc ignition and ARC FORCE to regulate the dynamics of the arc.

The device also has an optional VRD function that lowers the voltage in no-load condition and minimizes the risk of electric shock.

WORK CYCLE

The duty cycle is based on a 10-minute period. Duty cycle of 40% means that after 4 minutes of operation, a 6-minute break is required. 100% duty cycle means that the device can work continuously without interruption.

LEVEL OF SECURITY

The IP determines the degree to which the device is resistant to solid and water contamination entering the interior. IP21 means that the device is suitable for operation in closed rooms and is not suitable for use in rain and snow.

HOT START FUNCTION

The HOT START function is commonly known as hot start. It works when the arc is struck, causing the welding current to temporarily increase above the value set by the welder. HOT START is designed to prevent the electrode from sticking to the material and is a great help when starting the arc.

ANTI STICK FUNCTION

The ANTI STICK function is a short-circuit protection that reduces the welding current in case the electrode sticks to the workpiece. This makes it easier to detach and protects the device against damage.

ARC FORCE FUNCTION

It allows you to adjust the dynamics of the welding arc. Shortening the arc length is accompanied by an increase in the welding current, which stabilizes the arc.

Decreasing the function value results in a soft arc and a smaller penetration depth, while increasing the function value results in deeper penetration and the possibility of short arc welding.

With a high value of the ARC FORCE function, it is possible to weld with the minimum arc length and high electrode melting speed.

VRD FUNCTION

Module reducing the idle voltage of the device's secondary circuit. Increases safety and reduces the risk of electric shock. The function switches the welding power off and on when the resistance between the electrode tips - welded element is measured during welding.

APPLICATION CLASS

Application class S means that the device is adapted for use in places with increased risk of electric shock.

PROTECTION AGAINST OVERHEATING

The power source is equipped with a thermal automatic overload switch. When the temperature of the welding machine is too high, the protection will turn off the welding current and the overheating diode will light up). After the temperature has dropped, the switch will reset automatically.

TIG DC LIFT WELDING

Welding with a tungsten electrode in an inert gas shield using a torch with a gas valve in the handle.

The arc is struck by rubbing, similar to the MMA ignition method.

The use of this method enables the welding of all types of steel, i.e. carbon, alloy, stainless, acid-resistant steel, as well as copper alloys, e.g. bronze or brass.
