4-9. Arc Controls

1 Arc Control (Dig)

For AC And DC SMAW Welding

When set at 0, short-circuit amper- age at low arc voltage is the same as normal welding amperage.

When setting is increased, short- circuit amperage at low arc voltage increases.

Set at 0 for GTAW welding.

2 Arc Control Switch

Place switch in the ON position to turn on arc control circuitry. When switch is in the OFF position, no ad- ditional amperage is available at low arc voltages. Place switch in the OFF position while performing Gas Tungsten Arc Welding (GTAW).

Application:

Control helps arc starting or making vertical or overhead welds by in- creasing amperage at low arc volt- age, and reduces electrode sticking while welding.

4-10. Postflow Time Control

1 Postflow Time Control

Use control to set length of time (0–70 seconds) gas flows after welding stops. It is important to set enough time to allow gas to flow un-

1til after the tungsten and weld puddle has cooled down.

Application:

Postflow is required to cool tung- sten and weld, and to prevent con- tamination of tungsten and weld. In- crease postflow time if tungsten or weld are dark in appearance.

This capability is particularly valuable in high-volume settings, where efficiency and time-saving are crucial. The mixer is equipped with three fixed speeds, enabling operators to select the appropriate speed for different mixing tasks, from slow folding to high-speed whipping.

The bowl capacity of the OM-353 is another significant characteristic, accommodating up to 35 quarts. This large capacity is ideal for batch processing, allowing commercial kitchens to mix substantial quantities of ingredients simultaneously. The mixer features a sturdy stainless steel bowl, providing durability and resistance to wear while being easy to clean and maintain.

In terms of technology, the Hobart OM-353 incorporates a unique planetary mixing action that ensures thorough ingredient incorporation. The mixing attachments, which include a wire whip, flat beater, and dough hook, are designed to maximize efficiency and ensure every ingredient is evenly combined. The user controls are straightforward, featuring an easy-to-use lever for raising and lowering the bowl, along with a safety guard that prevents accidental operation.

Safety is a key consideration in the design of the OM-353. The mixer is equipped with an overload protection system that automatically shuts off the motor in case of excessive load, preventing potential damage. Additionally, its robust construction and stability reduce the risk of tipping during operation, ensuring a safe working environment.

The Hobart OM-353 embodies the ideal blend of power, performance, and safety, making it a staple in many professional kitchens. Its ability to adapt to various mixing needs, combined with its heavy-duty construction, ensures that chefs can rely on this mixer for consistent and high-quality results in their culinary creations.
