Types / Variants / Models
The Q-Gun series by Bernard features several modular variations built around amperage rating, neck type, handle style, cable length, and trigger configurations. The Q3015AE8EMC refers to a specific configuration:
– Q30 โ Indicates a 300-amp MIG gun.
– 15 โ Refers to a 15-foot cable length.
– A โ Straight handle style.
– E โ Rotatable neck.
– 8 โ Centefire Consumables.
– EMC โ Setup for .045 wire, Miller-style power pin for compatibility with Miller MIG welders, and conventional liner.
Other Common Variants:
– Q4012AE8CM โ 400A, 12-ft cable, centerfire consumables.
– Q3012AE4EMC โ 300A, smaller angled neck for tighter spaces.
– Q5015AE8 โ 500A version for high-amp, long-duration welds.
Each model serves a different purpose:
– Use lower amp variants (Q300) for medium fabrication and job shops.
– Use higher amp models (Q400/Q500) for heavy industry, shipbuilding, and structural steel.

Tips & Best Practices
Setup Tips:
– Always check compatibility with your machine’s power pin input.
– Use Centerfireโข contact tipsโinserting them with a simple push ensures electrical contact without tools.
Usage Tips:
– For spray transfer, ensure you use a proper shielding gas mix (e.g., 90% Argon/10% COโ).
– Clean contact tip and nozzle weekly to prevent spatter buildup and voltage drop.
Maintenance Tips:
– Replace liner every 2-3 months with heavy use.
– Apply anti-spatter solution to extend nozzle life.
Troubleshooting Tips:
– Erratic arc? Check for worn contact tip or dirty liner.
– Wire feed issues? Inspect the drive roll tension and liner path.
