What does 100 duty cycle mean on a welder?

What does 100 duty cycle mean on a welder?

Duty cycle is the percentage of time that a machine will safely operate (or weld), within a certain time period, at a given amperage. For example the Weldforce WF-205MST multi-function welder has a duty cycle of 200 Amps @ 30%. This means that it will operate at 200A for 3 minutes within a 10 minute time period.

Why is my stick welder not working?

One of the most common reasons your welder won’t spark is because the connection points between the welder and the metal pieces are not clean or clear. This means that both the workpiece where you want to form an arc as well as the connection point for the work lead clamp need to be bare metal.

How do you adjust current setting on the welding machine?

Push your foot down on the pedal to increase the amperage or let the pedal up to decrease the amperage, if your TIG welder has a foot pedal amperage control. Push the hand amperage control wheel forward to increase the amperage or roll it backwards to decrease the amperage, if your TIG welder has a hand control.

Why must a welding machine duty cycle never be exceeded?

Why must a welding machine duty cycle never be exceeded? Running a machine more than the stated duty cycle can ruin the welding machine easily. Duty cycles are limit for a machine. Using the welding machine above the stated rating will overload and overheat the welding machine.

Can you hold the rod while stick welding?

You can hold the electrode when stick welding (SMAW) for a short time to improve the electrode’s stability when striking the arc or making a few tack welds. When doing so, you must wear dry welding gloves in good condition.

What are the effects of too high or too low current setting?

If current on equipment is too high or too low, you are certain to be disappointed in your weld. If too high, the electrode melts too fast and your molten pool is large and irregular, if too low, there is nor enough heat to melt the base metal and your molten pool will be small, will pile up, look irregular.
