A VRD reduces the maximum open circuit voltage across the output terminals to below 15 volts
This is a safety requirement of most mines in South Africa when the unit is to be operated underground or in damp conditions
The presence of a VRD can however cause difficulty in the striking and re-striking of the arc with less skilled operators. This is because the machine has to rapidly change from the reduced open circuit voltage of below 15 volts to the open circuit voltage of around 56 volts necessary to strike the arc

All hire is charged at a daily rate. Many jobs run about three to five days, but you’re welcome to keep the equipment for as long as you need it. Hiring for a longer period? Just ask when you request your quote.
We deliver anywhere in Gauteng — to your site, home, or wherever you need it. Delivery is charged separately and isn’t included in the hire rate, but we’re glad to arrange it: just let us know when you request your quote.
Every item is serviced and checked before it goes out, and we handle all maintenance during your hire. We’d appreciate it back reasonably clean — but unlike some, we won’t charge a cleaning fee if it isn’t.
Once it’s with you, the equipment is in your care, so it’s up to you to insure it — we’re not able to cover hired items on our side. Everyday wear and tear is completely normal and nothing to worry about; we’d just ask you to look after it, as anything lost or damaged through mishandling would be for your account.
Our team is on hand during business hours for any questions, and we respond quickly to keep your project moving.
