Setup Guides
Get your ARCPEX machine up and running in minutes. Step-by-step setup for every model we make.
MIG200 — 6-in-1 Multi-Process
- 1Unbox and inspect: welder, MIG gun, ground clamp, power cable, gas hose
- 2Install wire spool: open side panel, mount 4"/8" spool, thread wire through drive roller to gun liner
- 3Set drive roller: match groove size to wire diameter (0.030" or 0.035")
- 4Connect gas: attach regulator to CO2/Argon tank, set flow to 15–25 CFH
- 5Select voltage: plug into 110V or 220V — machine auto-detects
- 6Set parameters: Voltage 1–4, Wire Speed 1–10 (start at mid-range for 1/8" mild steel)
- 7Attach ground clamp to workpiece, press trigger to feed wire, begin welding
MIG200 DP LCD — Dual Pulse
- 1Unbox: welder, Euro-connect MIG gun, ground clamp, gas hose, power cable
- 2Install wire spool and thread wire through drive roller to gun tip
- 3Connect shielding gas (75/25 Ar/CO2 for steel, 100% Argon for aluminum)
- 4Power on — LCD displays current program. Select material type on panel
- 5Use Synergic mode: set wire diameter + material — machine auto-sets voltage & speed
- 6Enable Dual Pulse: set Peak/Base current ratio and pulse frequency for aluminum
- 7Attach ground clamp, test weld on scrap, fine-tune as needed
DC TIG200 — Steel & Stainless
- 1Unbox: welder, TIG torch (WP-17), ground clamp, foot pedal (if included)
- 2Assemble TIG torch: install back cap, collet body, collet, and tungsten electrode
- 3Sharpen tungsten to a point (2% Thoriated or Lanthanated for DC welding)
- 4Connect torch to negative (-) terminal, ground clamp to positive (+)
- 5Connect 100% Argon gas, set flow to 15–20 CFH
- 6Select TIG mode, set amperage (1A per 0.001" material thickness as starting point)
- 7Enable HF Start, hold torch 1/8" from workpiece, press pedal to arc
ACDC TIG200P — Pulse Aluminum
- 1Unbox: welder, TIG torch, ground clamp, foot pedal, gas hose
- 2For aluminum: install pure tungsten (green) or Zirconiated (white), ball the tip slightly
- 3For steel/stainless: use 2% Lanthanated tungsten, sharpen to a point
- 4Connect torch to negative (-), ground to positive (+)
- 5Connect 100% Argon, set flow to 15–25 CFH
- 6Select AC mode for aluminum, DC for steel. Set Balance (AC cleaning: 25–35%)
- 7Enable Pulse if welding thin aluminum: set Peak 150A / Base 30A / 2Hz as starting point
- 8Press foot pedal to start arc, add filler rod at 15–20° angle
ARC200 DV — Stick / Lift TIG
- 1Unbox: welder, electrode holder, ground clamp, power cable
- 2Select electrode: E6013 for beginners / mild steel, E7018 for structural, E6011 for dirty metal
- 3Connect electrode holder to positive (+) terminal (DCEP for most electrodes)
- 4Connect ground clamp to negative (-) terminal and attach to clean workpiece
- 5Before connecting power, have a qualified electrician check the exact unit's label, plug, wiring, and intended supply, including circuit protection and grounding. The ARC200 manual specifies 110V ±15% input with 10–120A output adjustment, and 230V ±15% input with 10–200A adjustment. Voltage alone does not establish household breaker, outlet, or generator compatibility.
- 6Set amperage according to the applicable manual and electrode instructions, within the input-specific output adjustment range. Do not assume full 200A output on 110V input.
- 7Strike arc by tapping electrode on workpiece, maintain 1/8" arc length, drag at 10–15°
ARC140, ARC200 DV & MIG135 Power Checks
ARC140 is 110V-only per its linked manual: do not connect it to 220/240V. Confirm the exact ARC140 MINI model/version and applicable instructions before use. ARC200 DV's manual lists 110V ±15% input with 10–120A output adjustment and 230V ±15% input with 10–200A adjustment. MIG135's manual lists 110V ±10% input and 32A rated input current; this is not a breaker recommendation. Voltage alone does not establish US household breaker compatibility. A qualified electrician should check the exact unit's label, plug, wiring, and supply, including grounding and circuit protection. Do not assume any 15A/20A outlet or generator is suitable; generator and extension-cord suitability require verification. Follow the applicable approved instructions rather than assuming automatic voltage selection or universal connection compatibility.
First Weld = Test Weld
Always run a test bead on scrap metal before welding your actual workpiece.
Ground Clamp Placement
Attach ground as close to the weld area as possible for best arc stability.
Gas Flow Rate
15–25 CFH is the standard range. Increase slightly in windy or outdoor conditions.
