5.0 TORCH FUNCTION

Start to cut slowly, then increase the speed to obtain the desired cut quality . To start a cut on the sheetmetal border, align the center of the torch to the sheetmetal and press the start button: the arc cut will start on the border. Regulate the speed to obtain a good cut. Air plasma will create a straight arc (stainless steel alumi- num) or, a 5° arc Fig. E (Soft steel). The arc varies depending on speed, material and thickness.

5.1PERFORATION

In some cutting operations, it could be necessary to start the cut from a point dis- tant from the border. The backfire from this operation could shorten the life of torchs’ components. Therefore, it is suggested to do the job as fast as possible. When doing a perforation (Fig. F).

Slightly incline the torch, so that backfire particles are blown away by the nozzle (and by the operator) instead of bouncing back to the torch. Clean slag and incrostations from the protection bush. Spraying or inmerging the protection bush in an anti-slag substance, minimizes the quantity of incrostation that would stick to it.

NOTE! The following suggestions should be taken in consideration for all cut- ting operation.

a.After completion of all cutting operation, wait 5 minutes before shutting off the generator. It will give the fan time to cool and disperd the equipments’ heat.

b.In order for components to last longer, don’t let the arc pilot “ON” longer hen necessary.

c.Handle torch components with care and protect them from damages.

d.For material sostitution use only the safety tool.

READ FREQUENTLY OVER THE SAFETY PRECAUTIONS.

6.0COMMON CUTTING DEFECTS.

Trouble shooting for arc cutting operations:

Insufficient penetration.

a.Cutting speed too fast.

b.Not enough power.

c.Excessive material thickness.

d.Torch components damaged or worn.

Main arc goes off.

a.Cutting speed too slow.

b.Nozzle too distant from workpiece.

Slag formation.

a.Wrong gas pressure.

b.Wrong cutting power.

Burned nozzle.

a.Current too high.

b.Nozzle damaged or loose.

c.Nozzle touching the workpiece

d.Excessive slag: low gas plasma pressure.

7.0 TROUBLESHOOTING
