Strike Arc Inverter Welder 160A

The Strike-Arc 160A Inverter Welder is a high-performance, compact DC welding machine designed for both professional maintenance and serious DIY fabrication. Powered by advanced IGBT (Insulated Gate Bipolar Transistor) technology, it delivers a stable arc with superior penetration compared to older transformer-based units, making it an essential tool for gate repairs, fencing, and steelwork in the Heidelberg region.

Technical Specifications

• Current Range: 20A – 160A (Infinitely adjustable).
• Input Voltage: 230V / 50Hz (Standard single-phase household power).
• Duty Cycle: 60% at 160A (Allows for 6 minutes of continuous welding in a 10-minute cycle).
• Electrode Size: Optimized for 2.0mm, 2.5mm, and 3.2mm welding rods.
• Protection Rating: IP21S (Protected against vertical water drops and small solid objects).

Key Performance Features

• Hot Start Technology: Provides an automated boost of current during arc ignition, preventing the electrode from sticking—ideal for cold starts during the Winter 2026 season.
• Arc Force Control: Automatically adjusts voltage to maintain a smooth, consistent arc, even if the distance between the rod and the metal varies slightly.
• Anti-Stick Function: If the rod sticks to the workpiece, the machine immediately drops the current to prevent the electrode from overheating or becoming unusable.
• Portable Design: Lightweight enough to carry up a ladder, it includes a heavy-duty shoulder strap for working on Stafix fencing or elevated JoJo Tank stands.
• Thermal Overload Protection: Internal sensors shut the unit down if it exceeds safe operating temperatures, protecting the electronics during high-demand Easter 2026 projects.

Professional Usage & Tips

• Power Supply: For maximum output, use a dedicated 15A wall socket. If using an extension lead, ensure it is a heavy-duty 2.5mm core cable to avoid voltage drops that weaken the arc.
• Electrode Selection: For general mild steel (angle iron or square tubing), use 6013 "Easy-Strike" electrodes. Use 2.5mm rods for thin-wall tubing and 3.2mm rods for heavier base plates.
• Earth Connection: Always grind the metal to a bright finish where you attach the earth clamp. A poor connection is the primary cause of excessive "splatter" and inconsistent welds.
• Cooling Down: After finishing a job, leave the machine switched On for 2 minutes before unplugging. This allows the fan to cool the internal components gradually.
• Safety Gear: Never weld without a Strike-Arc Auto-Darkening Helmet and Dromex Leather Welding Gloves. Inverter arcs are extremely bright and produce high UV radiation.

Common Use Cases

• Agricultural Repairs: Fixing cattle kraals, trailers, and farm implements.
• Security Fabrication: Building burglar bars, pedestrian gates, and palisade fencing.
• DIY Projects: Custom metal furniture, bracket fabrication, and hobbyist art.
• Maintenance: On-site repairs for Pascali Pump cages and industrial shelving.

Pro Tip: Keep your welding rods dry. In the humid Gauteng summer, electrodes can absorb moisture, leading to "porosity" (tiny bubbles) in your weld. Store your rods in a sealed PVC tube or a Wildebees ammo box with silica gel to ensure a perfect strike every time.
