  • Inspect power cable & connections
  • Check gas hose for leaks
  • Clean nozzle & remove spatter
  • Verify ground clamp contact
  • Check contact tip for wear

📅 Weekly

  • Blow dust from vents (dry air only)
  • Inspect wire feed rollers & tension
  • Check liner for kinks or blockage
  • Inspect torch body for cracks
  • Test all controls & switches

🔧 Monthly

  • Deep clean interior with dry air
  • Replace worn consumables
  • Check all electrical connections
  • Lubricate wire feed mechanism
  • Test thermal overload protection

📦 Storage

  • Store in dry, dust-free environment
  • Cover machine when not in use
  • Remove wire spool for long storage
  • Close gas valve & release pressure
  • Run machine briefly every 2–4 weeks
Machine-Specific Maintenance
MIG

MIG200 & MIG200 DP LCD

After Every Use

  • Remove spatter from nozzle with nozzle reamer or pliers
  • Apply anti-spatter spray inside nozzle
  • Check contact tip — replace if hole is oval or worn
  • Release wire tension on drive roller

Monthly

  • Replace MIG gun liner every 3–6 months (or when wire feeds rough)
  • Inspect drive roller groove — replace if worn flat
  • Check Euro connector O-ring for gas leaks
  • MIG200 DP LCD: clean LCD panel with dry cloth, check knob contacts

Consumables to Stock

  • Contact tips (0.030" / 0.035")
  • MIG nozzles (standard & tapered)
  • Gun liner (15ft / 10ft)
  • Drive rollers (V-groove for steel, U-groove for aluminum)
TIG

DC TIG200 & ACDC TIG200P

After Every Use

  • Remove tungsten and clean collet body
  • Inspect back cap O-ring for gas leaks
  • Wipe torch body with dry cloth
  • Close argon tank valve, bleed hose pressure

Monthly

  • Replace collet & collet body if tungsten slips or arc wanders
  • Inspect torch head for cracks or discoloration
  • Check foot pedal cable connector for bent pins
  • ACDC TIG200P: verify AC Balance setting resets correctly on power cycle

Tungsten Care

  • DC welding: re-sharpen tungsten when tip becomes contaminated
  • AC aluminum: re-ball tungsten tip if it becomes irregular
  • Never grind tungsten across the grain — always lengthwise
Stick

ARC200 DV

After Every Use

  • Remove electrode stub from holder
  • Chip slag from weld area before inspecting
  • Inspect electrode holder jaw for carbon buildup
  • Coil and store cables without sharp bends

Monthly

  • Clean electrode holder jaws with wire brush
  • Inspect ground clamp jaw spring tension
  • Check power cable insulation for cuts or burns
  • Blow out internal vents with dry compressed air

Electrode Storage

  • Store low-hydrogen electrodes (E7018) in a rod oven at 250–300°F
  • Keep E6013 in sealed container away from moisture
  • Discard electrodes with damaged flux coating
