🎯 Which One Should You Choose?
🔵 Choose MIG200 ($399.99) if you:
- Are a beginner or intermediate welder
- Weld mild steel, stainless, or flux core
- Have a budget under $500
- Need a versatile 6-in-1 machine
- Weld aluminum occasionally via spool gun
- Work in a home garage or small shop
🔴 Choose MIG200 DP LCD ($799.99) if you:
- Weld aluminum frequently or professionally
- Need dual pulse for clean aluminum beads
- Want memory presets for repeat jobs
- Prefer a full LCD display for precision
- Run a professional fabrication shop
- Work on boats, RVs, or aerospace parts
❓ MIG Welder FAQ
How thick can the MIG200 weld on 110V vs 220V?
On 110V, the MIG200 welds up to 3mm (1/8") mild steel. On 220V, it handles up to 6mm (1/4") mild steel. For thicker material, use multiple passes or preheat the base metal.
What is the duty cycle and will the MIG200 overheat?
Both MIG welders have a 40% duty cycle at 200A — 4 minutes of welding followed by 6 minutes of cooling per 10-minute window. The smart thermal protection automatically shuts down before damage occurs.
Can I weld aluminum with the MIG200?
Yes. The MIG200 supports aluminum welding via a spool gun (sold separately). For native aluminum welding, the MIG200 DP LCD with dual pulse delivers cleaner, more consistent aluminum beads.
What circuit breaker do I need for 220V operation?
For the MIG200 on 220V, use a dedicated 30A circuit breaker. For the MIG200 DP LCD, use a 40A breaker. Avoid extension cords longer than 25 feet.
What shielding gas do I need for MIG welding steel?
For mild steel, use C25 (75% Argon / 25% CO₂) at 15–20 CFH. For aluminum, use 100% Argon at 20–30 CFH. No gas needed for flux core welding.
Can I use these MIG welders indoors and outdoors?
Yes. Both welders work indoors and outdoors. For outdoor use, switch to flux core wire — wind can disrupt shielding gas. Ensure adequate ventilation indoors.
