Q 1. What materials can the SIP 05789 cut?

A. The 05789 cuts any electrically conductive material including mild steel, stainless steel, aluminium, copper, and brass. Maximum cut capacity is 20mm. It cannot cut non-conductive materials such as wood, plastic, or ceramics.

Q 2. Does the SIP 05789 require a 3-phase supply?

A. Yes. The 05789 requires a 3-phase 400V supply and must be hardwired by a qualified electrician. It is designed for professional workshop and industrial environments where 3-phase power is available.

Q 3. What is the duty cycle of the SIP 05789?

A. The 05789 has a duty cycle of 70A @ 60%. Duty cycle is measured over a 10-minute period — a 60% duty cycle means 6 minutes of continuous welding followed by a 4-minute cool-down. Operating at lower amperages increases available run time.

Q 4. What is supplied with the SIP 05789?

A. The 05789 is supplied with the accessories needed to start welding — check the product listing for the complete included items. Additional consumables for the 05789 are available at PartsForMachines.com.

Q 5. Is the SIP 05789 suitable for site or mobile use?

A. The 05789 is primarily designed for workshop use. Check the specification for weight and portability details.

Q 6. Can the SIP 05789 cut aluminium?

A. Yes. The 05789 cuts aluminium along with mild steel, stainless steel, copper, and brass. Plasma cutting works on any electrically conductive material — non-conductive materials cannot be plasma cut.

Q 7. Does the SIP 05789 have thermal overload protection?

A. Yes. The 05789 is fitted with automatic thermal overload protection that cuts output if the machine exceeds safe operating temperature. It will restart automatically once it has cooled. Operating within the rated duty cycle minimises the frequency of thermal interruptions.

Q 8. Can the SIP 05789 cut painted or rusted metal?

A. A clean bare-metal contact point is generally needed to start the plasma arc reliably. For painted or coated surfaces, cleaning the start point is recommended.

Q 9. What thickness of metal can the SIP 05789 cut?

A. The 05789 cuts any electrically conductive material — mild steel, stainless steel, aluminium, copper, and brass — up to its rated maximum thickness. For best edge quality, cut at around 60–70% of maximum rated thickness. Thicker material can be severed but the edge will be rougher and may need grinding.
